So again need expert advice. Due to surgeries I’ve been out of the shop but rebuilt and good to go. Got my built 351 SERP (not Explorer) with C4 installed in stock 66 body with 2” body lift. On my last 351 SERP install I modified the radiator supports to move radiator forward for SERP clearance. Before doing this I wanted to ask if any new radiator options that might fit stock supports. Proform Slim fit model gives me SERP clearance, but pricey and too wide. Pics show my stock radiator support sizes. Thanks.
