Re: 9 3/8" posi and 3.91 gears for 61-62-63 Buick full size Electra,LeSabre,Invicta,W just out of curiosity, is that a Salisbury or Hotchkiss type of rear end assembly?? local yard is parting / selling a 65 convertible, has a huge rear under it, with drop out center section - hotchkiss type. am going to guess earlier sixties Buick full size - pre 65 used an X frame similar to the 58 - 64 Chevrolet type.
Re: 9 3/8" posi and 3.91 gears for 61-62-63 Buick full size Electra,LeSabre,Invicta,W Yes, Hotchkiss front loaded center section.
Re: 9 3/8" posi and 3.91 gears for 61-62-63 Buick full size Electra,LeSabre,Invicta,W Hey Tom, just FYI, the '63 posi unit is different than those used in '61 and '62. The '63 unit is 30 spline, and '61 and '62 unit is 33 spline. And good luck finding a gear set, something that low is beyond rare! :beer
Re: 9 3/8" posi and 3.91 gears for 61-62-63 Buick full size Electra,LeSabre,Invicta,W If this starts to look like it's going to be a pain in my ass finding parts, the car will get an early Olds/Pontiac rear, and I'll be done messing around. If someone has parts, I have money
Re: 9 3/8" posi and 3.91 gears for 61-62-63 Buick full size Electra,LeSabre,Invicta,W Tom.....there are only 4 or 5 sets of 3.91's that i have ever know of in the last 30 years. I have two and a friend has two plus i think i know of one more out there. I will consider selling one of my sets...... Too bad we can't find the 4.45's that i sold to someone here on V8.......those were the drag racing gears......got them from Kenne-Bell in '75 and TOPCAT was a stop light TERROR in Grand Rapids Michigan the next couple years while i went to Technician's school :grin: Peace WildBill
Re: 9 3/8" posi and 3.91 gears for 61-62-63 Buick full size Electra,LeSabre,Invicta,W do you think a 62 lesabre 4 door with a 401 and a 2 speed auto would have them?
Re: 9 3/8" posi and 3.91 gears for 61-62-63 Buick full size Electra,LeSabre,Invicta,W Gary....probably not........but if the car has a big trailer hitch on the back......it's worth a look......those were actually trailer towing gear sets........sometimes a big hitch means big gears.....:Brow: Peace WildBill
Re: 9 3/8" posi and 3.91 gears for 61-62-63 Buick full size Electra,LeSabre,Invicta,W Thanks guys, I knew going into this that it was going to be the road less traveled, and some of the parts were going to be tricky to obtain. Heck, the car is going on 52 yrs old, so just the rate of how many have been scrapped over the years limits the ammount of parts left available, the average age of people who own/have owned these cars,gotten out of the old car hobby is of the older crowd. Anyways, thanks for the help,I appreciate it.
Re: 9 3/8" posi and 3.91 gears for 61-62-63 Buick full size Electra,LeSabre,Invicta,W here is the car can you post a pic of what I need to look for on the rear end will go tommorow there http://www.v8buick.com/showthread.p...door-in-yard&p=2102765&highlight=#post2102765
Re: 9 3/8" posi and 3.91 gears for 61-62-63 Buick full size Electra,LeSabre,Invicta,W There won't be any visible stampings on the housing. You'd have to rotate a drum and count the number of rotations of the driveshaft per rotation of the drum. That's also the easiest way to check for a posi. I'd suspect the LeSabre has 3.23's, or maybe 2.78's.
Re: 9 3/8" posi and 3.91 gears for 61-62-63 Buick full size Electra,LeSabre,Invicta,W Stock ratio was 2.78 for 401 with 2 bbl carb and 3.23 for 401 with 4 bbl carb (Power Pack) in the LeSabre for 1962.
Re: 9 3/8" posi and 3.91 gears for 61-62-63 Buick full size Electra,LeSabre,Invicta,W Ttt $$$$$$$$$$$$$ ???????????:tu:
Re: 9 3/8" posi and 3.91 gears for 61-62-63 Buick full size Electra,LeSabre,Invicta,W You will also need the "Posi" unit that goes with the 3.42 gears & up. Little easier to find than the 3.90's/91's or the 4.45's. You could make a spacer that's about 1/4" thick. Then you need longer ring gear bolts to convert 3.23 & back posi unit's.
Re: 9 3/8" posi and 3.91 gears for 61-62-63 Buick full size Electra,LeSabre,Invicta,W This rear end issue may be the deciding factor of which way I go with this project, or if I even go ANY further with it. Either somebody sell me a rear, or come buy the car:shock:
Re: 9 3/8" posi and 3.91 gears for 61-62-63 Buick full size Electra,LeSabre,Invicta,W have you looked into having a ford 9" built for the car? A lot more parts for much better prices. How much for the car? pictures? Rust?
Re: 9 3/8" posi and 3.91 gears for 61-62-63 Buick full size Electra,LeSabre,Invicta,W They make Ford 9in housing for '59-'64 GM B-Bodies. Although it wouldn't be bolt in, it should be close enough to work with relatively little modification.
Re: 9 3/8" posi and 3.91 gears for 61-62-63 Buick full size Electra,LeSabre,Invicta,W I'd like to see pictures anyway.. One of my favorite years and bodystyles....
