Will 89-90 fenders fit on a 91-94 240SX?
Yes just take the plastic filler pieces off the 91-94 fender and put them on the 89-90
The question was refering to the other way around, the earlier fenders on the later cars, but Im assuming thats a yes too…
Yes the 91-93 have an extra piece that the other years dont thats why you take it off and put it on the 89-90 fenders if you are putting the 89-90 fenders on a 91-93.
Will a 89-90 door fit on a 91-94 240SX?
Yah it will. You just won’t have the plastic filler piece I guess. Or at least I think that’s what Nis240 was getting at.
