ive got the a2, and AC. There arent any clearance issuse that i ran into with my swap, except i hard to lower my engine in at a 45 degree angle so i wouldnt have to decompress the lines, it was a ghetto, but it saved me like 40 bucks. Ive got some pictures somewhere, maybe ill find them and post them if you want. the AC fan on the otherhand does have some clearance problems...i had to take mine out but i dont have any overheating problems, im more of a roll down the window kinda guy.
