My boy's first Mopar!

just returned from offshore , salvaged a platform that was downed in hurricane Ike . Ordered some goodies from US car Tool ( chassis stiffening kit) , which should be here in a couple days . One of the items in the kit is the radiator support brace ...which got me to looking at the one in the car now ... Our car came with a slant six and so it has a small radiator opening ... we will be upgrading to a V8 and obviously would benefit from a larger radiator . We have a parts car that had a 26" radiator from the factory that I could remove the radiator brace from . Any advice on swapping out the braces ? where to drill spot welds etc .? we will be welding in the sub frame connectors and torque boxes later this week , just wanted some input on the radiator before I tore into it ... any recommendations on the Radiator itself? Probably will add A/C to this car before it's over with too. Rich
