    Finally Got the swap done!

    4 Speed M20 in my 1970 Skylark with a 350.

    69 M20
    TA Flywheel
    Centerforce Dual friction Clutch
    Speedway Motor Hydraulic throwout bearing
    American Powertrain Clutch Master cylinder bracket
    Wilwood Master Cylinder and reservoir Kit

    Came out pretty good!

    I also was able to get a nice deal on a consolette. I also sourced all the hardware from @ToddsGS . It made the whole swap easier. Clutch switch and harness, boots, etc all worked out great!

    Now I am thinking of making my own console with cup holders. I also want to get a nice tach to drop into my consolette as well.

    The car is still a turd since it has the 2.56 open rear but I finally sourced an 8.5 out of a 72 skylark but I am deciding on what gears to drop into it. I have 3.23 gears on the table with a 30 spline carrier, but I might as well just order a new 28 spline carrier and transplant the 3.23 or maybe get some 3.42s

    I don't want to burn my clutch up since it takes some RPMs to get it moving but once im in the powerband, it pulls hard. Highway cruising is awesome but I need to be able to take off the line.

    I am still happy with the swap. I never thought I would have a manual skylark anytime soon.

    Does the shifter position seem okay? Anyone have a cheap 28 spline carrier they might want to sell?

    Nice swap. I used the complete American Powertrain hydraulic kit when I converted my 67 Skylark. Looking back....I would do it the way you did and probably saved myself some cash.

    Looks good, I'm in the process of installing A 4 speed in my 72.
    I saved up parts for about two years and decided to go for it.

    With that trans, I don't know that you can really change the location of the shifter? The only thing that looks odd is the boot on the bottom. I think technically it should have the hump welded in the floor, but I'm no expert. That works fine thou, and was less invasive. My 68 is a 5spd, 3:77 gears. Its great. all around with the OD. That Consolette is the bomb. I would love to find one of those, I could afford. Put a dash tack in it, you wont like having to look down to see it when your really getting into it.

    Another update:

    Ordered a Yukon carrier and some 3.42 gears.

    Turns out they installed the spare Chevelle shifter handle I had instead of the Buick one I had purchased. That's why it's closer than I thought! I wonder if it's possible to swap it while in the car.

    For sure, if it is the insert and clip type that does not use bolts. I cannot say from personal experience for the bolt in type.

    If yours has a pawl retaining clip, use a little lube with about a 16/1000 feeler and insert it on the passenger side of the lever to release.

    I'll take a closer look, this is what it looked like before the boot etc, I totally forgot to check the shifter arm at the time I took the picture. 20200221_155256.jpg

    Welp, took the console apart and it turns out the shifter I have is a bolt in configuration.

    Would it be safe to drill a second home and bolt it up?

    I had no Idea Buicks had clip in style, just threw a wrench into the swap again -_-

    It seems so high in the air.

    That one is actually shorter than the stock one I have. Unless the area where the stick mounts to is supposed to be shorter.

    The stick height is 13.5 inches

    Vs the 11 inch stick that's on it.

    Picked up a shifter that is exactly the same style but shorter. I'll drill the original when I'm back to work but so far it actually looks and feels nice. 20200327_202538.jpg

    Very nice. How'd you calculate where to place the holes for mounting the console. Mine might be too far back.

    Honestly, I just installed the shifter and handle then placed the console over it. I then made sure the shifter wouldn't hit the console in all gears and marked it, and boom drilled into the tunnel.

    I also used this real Stage 1 4 speed GSX as a reference. Got lucky and got to visit a gentleman that had it tucked away.
