Oh stop it! I'm just kidding. It's cheaper to get a universal one and modify it and the surrounding area to fit. This is for a 51 merc that I put an Impala SS LT1+4L60E into. By the way that color is plum crazy and it's pretty! The header piece had to be pie cut and welded back with no assist from Mr. Bondo. The top edges were lopped off of the radiator to help fitment. The lower neck was cut and a smaller neck was installed. Four tabs were welded on to the radiator for mounting. The drain cock was installed and the cradle was modified with cut outs for the necks and drain and tabs to mount the radiator. Not pictured is the filler neck. Installed pics will come soon!
