yup. on a 1991, the biggest size u can get are 24x8. i have them on my 1991 caprice
not without a lift kit but if determined you can make any thing fit
Any 1977-85 Impala or 1977-90 Caprice will work
Any other grille from a 1977-79 Caprice/Impala would be a good fit
No
The Caprice has never had any major history of transmission trouble. One can deduct then that the transmissions are stable.
A Caprice steering column can be replaced by another as long as it matches. It if comes from another Caprice of that year, it will fit properly.
two9s here i have a 91 caprice with 22 inch rims. so the answer to your question is YES. the 91 and 92 caprice can fit 22 inch wheels with the tire size 265 35 22 with out any modifications as long as the offset is correct to match the width of the rim. my rims are 22 by 9.5 with a five inch lip and the rims have a positive 18mm offset. i have about a quarter inch space on either side of the wheel under the skirt. if the rims were not made specifically for your car try a smaller width (like 9 or 8.5) to be safe. also if the vehicle does not have the police package (stiffer suspension) it may rub the top of the tires over deeper bumps.
5w30 any major brand
ive seen caprice,s with zz572 big blocks. pretty much any motor will fit
Any door from a 1977-79 Caprice/Impala would fit (assuming it's a similar bodystyle)
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
Any constant vacuum source.
