Nope; can't compare them, their on eBay. But I think it's worth taking a chance, too late anyways, I just made my bid, so we'll see if I get them...

OK, and how about a '92? Are they interchangeable in the 91 as well? Reason, I'm asking is that i've found a used set of four window motors('90 and '92) for about a hundred bucks. Might as well get the newer ones if their the same and heck; that's a good price.

Anybody know if an electric window motor removed from a 1990 classic will work properly in a 1991 classic?

You better pull up floor mats and carpet and check for corrossion underneath. Same thing happened to me with my 1991 classic, and the floorboards were completely rusted.

There's lots of good reasons to swap out engine and trani; all depends on how you use the vehicle. If your car is running fine, and you use roads that are mostly paved and in good condition, do you really need to change a thing? For me it breaks down like this: 1. 50% of the driving time...

OK....thanks. That's something to look into...

Looking for some advice for "those in the know..." I live in Costa Rica, where parts and good maintenance are a hard bargain! Anyway, I've recently acquired a 1991 RR that has spent half its life parked. Surprisingly, it fired right up when I put in the new battery. Has 150k miles and runs ok...
