So my 72 started to run a little warm when I installed the sniper FI. After some research I realised I still have the original 6cy radiator set-up and it was never upgraded when the PO put the 302 in. So I order a new AL 3 Core from Toms but I trying to figure out how to mount it. I will need the mounts they sell as well but how does all that attach to my current set-up. I think i know where the top mounts will go (see in attached photo??) but I do not see where the bottom mounts go....do I need to weld some type of cross member below?
