Core Support questions...

[72blaz]

I have a 1972 Blazer..yet I think that the PO put a 68 front clip on it.. There was definatelly a 68 grill on it...but it wasn't installed properly..(Zip ties)...so I'm close to getting it painted..and not long after will be the process of grills..etc....so my question is this..besides the grille style...what other differences should I be aware of with a 68 core support on a 72 blazer....will there be major problems down the road?.. should I go ahead and get a 72 core support now..(Body hasn't been put back together yet)... does it matter at all?...etc..etc... Any help would be greatly appreciated.. ............as I was.... I think from the only side picture I have.. that I may indeed have a 72 core support...but the PO tried to rig a 68 grille in there without knowing what the hell he was doing....no picture of the front..so I'll have to go snap another one to make absolutly positive...but I am 90% sure from this angle that it's a 72 support.
