I ordered one of the Silla radiators off e-bay (184.95, free shipping). DavieGravie and I put in in my 92 Liquid Silver this past Saturday. It fit perfectly; everything matched up with no mods required at all. It was a clone of the OEM unit it replaced.
The only issue was they dicked around and did not ship quickly.....ordered and paid for on a Sunday morning, and did not ship until the following Thursday. When I called their toll free number, I got some damn foreigner who could not speak ENGLISH! Imagine that!
No probs with the radiator itself....
