Frequently asked questions about 4 speed parts..PLEASE ADD TO THIS!!

Ok does anybody need 69 rod's? Swap for 70-72???:TU:

 

An original 1970 GS 455 4 speed non-console boot, thanks to Steve Weiman, Rocky Mountain Buick GS club.

 

Does that finish with a chrome moulded trim ring?

 

Mark- every one of the lower boot rings I have seen were either black painted or black phosphate coated.

 

Important to mention that the ring is underneath the outer flap, so it is not visible. The picture would be correct.

 

Does anyone have an pic of a 70-72 floor pan with the correct bracket for the D56 "short non-shift floor console" / storage console for bucket seat cars without the full length console? A drawing of the bracket is on page 1-12.1 of the 70 assembly manual. I am trying to locate the correct position of the bracket and was hoping to see an original so I can at least get close. Thanks.

 

I just wanted to add a few things here, being ate up with four-gears for a long time.

First, the B-O-P bell housings without the pivot ball stud are mostly from V-6 Vega body cars. They used a cable style clutch, usually with fork came out the opposite side.

Second, in my experience the clutch pedal assemblies are '64-'65 '66-'67 and '68-'72. In most instances the '64-'67 will inter change. *(On pretty much all A-body stuff) There are some slight changes in the pedal shapes and bends.

Third, the clutch cross shaft/bell crank/z-bar is '64-'65 '66-'67 amd '68-'72. The main difference is a bend to clear the change to a collapse-able sterring column in '67. The BOP z-bars (OEM ones) are multiple link deals to allow for the motor to torque over, where the Chevy one don't. In the cars I have converted, I used Chevy Z-bars, because, well, the were already in the reproduction market.

The question I have, any of you '64-'67 guys have header issues? I have ran into this with a '65 442 and a '67 442. All the rest of the A-bodies and X-bodies I have converted went ok.

 

Hey there gd2227 and all of our Buick friends,

I need some good pictures of the floor area with the carpet removed -- I'm converting a '69 Skylark from an automatic transmission shifted on the column to a four-on-the-floor. This one picture you have of the hump alone is helpful -- anyone have some good pictures of the whole floor with the hump from various angles?

I'm installing a Muncie M-21 and a Buick consolette.
Thanks! Take care.

 

Any thoughts on the retaining ring?? There are enough 68 -72 4 speeds out there to repro, I would think, let alone the conversions. Thanks

 

OK, are you selling these parts, or is anyone; if so, please let me know who to contact, thanks!

 

I am certain Jim (flynbuick) was posting the pic for reference. Let me work on getting some links posted for the above requests...

 

OK... Using the words 'floor hump' after clicking on 'search' under the V8BUICK banner:

Attached is a link for Parts place and the repop clutch fork. It says it's a direct replacement for specific years to include 71. Is this an exact reproduction? Does it have the hole for the spring? I also included the picture.

If not

Think GM corporate. I have a 68 4-4-2 floor shift, the boot was trash. After years of searching for a good used I found a nice one, paid $150. Within a week I discovered that it was being repro'd for $50. It is identical to the one pictured. it was used on Olds bench/bucket console free cars. If you think about the GM philosophy, it makes sense to share low production parts. I just discovered that Firebird hinges fit my Cutlass. Anyway, try Fusick Auto for the boot.

 

'70 Hurst competition plus shifter .
Housing 3138, shim, lever 6699, shim, lever 7171, lever 4172 ,shim,
Bushing, carriage bolt, dust cover 2497 side cover 2480. internal shifter plate.

Not pictured: receiver, bolt plate, lock nut and nylon washer.

 

What year is this and is it a console or non-console cover?

 

For all the 4 speed experts;

OK, I'm going to ask this question considering I'm confused as to the type of Muncie (M20/M21/M22) transmission that came factory with the 71 Stage 1 cars. After looking at 5Speed.com and various threads about the subject I've come to the conclusion that there's a difference of opinion. After looking at the information in detail it seems that 70 and 71 had a mix of transmissions and gear ratios as you'll see below.

SUBJECT CAR;

1971 Buick Stage 1
3:42 rear gears
Air conditioning
Muncie M? transmission

Three questions;

1) What Muncie transmission and gear ratios came factory with the 71 Stage 1?
2) What would be the preferred Muncie transmission and gear ratio for a 71 Stage 1 - for best performance?
3) Did the 71 GSX Stage 1 have a different transmission/gear ratio configuration? If so, what was it?

Ratios of the M20 , M21 , M22

Year 1963-1965 Type: M20 Rings: None Ratio: 2.56 / 1.91 / 1.48 / 1.00 / 3.16
Year 1966-1974 Type: M20 Rings: Two Ratio: 2.52 / 1.88 / 1.46 / 1.00 / 3.11
Year 1963-1974 Type: M21 Rings: One Ratio: 2.20 / 1.64 / 1.28 / 1.00 / 2.27
Year 1967-1974 Type: M22 Rings: None Ratio: 2.20 / 1.64 / 1.28 / 1.00 / 2.27


Input Shaft Tooth and Spline Count Related to Year

Year 1963-1965 Type: M20 Rings: None Spline: 10 Tooth Count: 24
Year 1966-1970 Type: M20 Rings: Two Spline: 10 Tooth Count: 21
Year 1970-1974 Type: M20 Rings: Two Spline: 26 Tooth Count: 21
Year 1963-1970 Type: M21 Rings: One Spline: 10 Tooth Count: 26
Year 1970-1974 Type: M21 Rings: One Spline: 26 Tooth Count: 26
Year 1967-1970 Type: M22 Rings: None Spline: 10 Tooth Count: 26
Year 1969-1974 Type: M22 Rings: None Spline: 26 Tooth Count: 26

 

Would have been a m21 with 26input 32 output, 70 and back was m21 10spline and 71 up was 26 spline, as far as what ive seen anyway

 

Excellent, thank you.

Hugger is right.Until I see proper documentation that any Buick received an M22,it's just a myth. I had a discussion awhile back on the topic of the M22 and if it ever was an option. And there is no way I would believe a stamping as I have seen a couple.4 speed housings unstamped without any VIN..I want to see a buildsheet or something..I agree that the M21 would be the best transmission for your car too.. I have an M20 that I have from an old GS 400 68 car that I put in my 73 GS as it had a new clutch and pressure plate.That was a bad idea as it can hardly get out of it's own way when I take off. I have 3.42's in that as well as a 350 motor. The transmission will be getting replaced as soon as nice weather arrives.
