sedan is 5x4.75
station wagon is 5x5
In 1991 all B-bodies switched to a 5x5 pattern.
yes
I have a 90' Caprice with a 305 that I brought up to 130mph.
1955-up same Chevy and gmc with 90 degree bellhousing pattern.
depends on what year, 90 and older had 5x4.75 bolt pattern like older Monte carlos, 1991 and newer have 5x5 bolt pattern like half ton trucks and some vans
Not without modification
in the fuel tank, its like $90 at carquest
The 91-96 Buick Roadmaster as well as the rest of the b-body (Impala ss Caprice Fleetwood) line have 5x5 bolt pattern same as 90's models 2 wheel drive tahoes and silverado pick ups
Actually yes it will. Caprice/Impalas from 1977-1996 Share the same basic chassis. It will fit, also how do I know for a fact? I have a 9c1 rear end in my 88 caprice. Also just about any and all Suspension parts from a 91-96 caprice/impala will work with a 77-90 caprice/impala. However you will now have two different bolt patterns, unless you have a 80's 9c1 police package caprice which I believe did come with the same 5x5 bolt pattern as the 91's caprice/impalas
All chevy 350 engines use the same bolt pattern to bolt the bell housing to the block so the 71 model block should bolt up the same although there may be slight differences otherwise.
not without significant modification. The width is wrong and the trailarm mounting locations are all wrong. You would be better off finding an 8 7/8" 10 bolt posi out of a 77-90 wagon (though the wheel bolt pattern is 5" instead of 4.75"). I have also heard that with the exception of the ABS sensor mounted in the nose of the gear housing, the 91-96 B body rears will also fit (all 91-96 B bodies are 5" bolt pattern as well).
Pontiac Chevy PU motor switchIf you try hard enough. Depends on what transmission is in the truck. Some had duel bolt pattern where the motor and trans. bolt together. Chevy has a different pattern than all othe GM's All other GM's interchange except for Chevy. Chevy, all motors, rear wheel drive will interchange, 1955 to at least mid 90's probably current.
Yes
