The doors off a 94 Chevy S10 will fit on a 94 GMC Sonoma with minor modifications. Both use a very similar body design which is largely only different in cosmetic features.
Yes, Same engine.
yes
Yes it should. cavalier/corsica 90-95; most parts will be interchangeable.
if it is the same motor yes, but some may have different mounts or wiring plugs
Not if you want a tire sidewall any higher than the thickness of a dime.
well according to autozones website, no. they are different part numbers from 89 to 94 in both four and six cylinder engines
My friend, it is important that you get a shop manual for this job, if you are the one to do it. It doesn't take a rocket-scientist but one has to know much about how an engine works and safety. Now, if your'e asking bcuz you are going to do it and kow quite some on the subject, You really need to consult with a shop manual. Your question indicates to me that you have never done this work. So be very careful and good luck. There is no 1991 sunfire, it was the sunbird until 1996. Actually, the Sunbird only went thru '94. The Sunfire showed up for '95. (I know, I own one! :) Well correct me if I'm wrong but I don't think the Cavalier/Sunbird/Sunfire had a timing belt I thought they had timing chains. If I remember correctly thru 94 cavalier 4cl has the timing chain and sunbird has a timing belt. 95 and up cavalier/sunfire has a timing chain.
Well, Pontiac didnt make a sunfire in 1994 is it a 95 sunfire or 94 sunbird?
