Yeah the early A's are a bit narrower than the late. You found out the hard way.
Looks like I get to do some grinding
I've got a BE COOL in mine. I made a bracket before I found there was a bracket for it. I bought the bracket from be cool and it looks like a direct fit, but I haven't put it on yet. I don't think this picture shows it very well. MOE
Did a little die grinding surgery today. Had to notch the lip on both frame wells then cut out some of the core supports. Seems the original radiator mount on the drivers side was sticking out farther than the other. Think that is the way it was factory or the core support was tweaked.
BeCool radiator is sitting in pretty nice now just need to mount a trans cooler and I can bolt this radiator in.
