Mix-n-Match - Del-a-lum & poly?

[tripower]

I'm in the process of putting together new suspension pieces for my 65 GTO and was looking at GW & Hotckis of front upper As. If I go the GW route, the Del-a-lums sound like they may be the way to go. Is this overkill? The car will be used for street duty and possible 1/4 mile blasts. Based on that use, would poly be sufficient?

Next question; If I go the del-a-lum route up front, do you have to stay with GWs rear pieces also equipped with d-a-l bushings or can you go with, say, Hotchkis or E-brock rears utilizing poly bushings? I believe I read on the GW site that the car wouldn't handle correctly mixing and matching del-a-lum and poly front to rear. Is this true?



Thanks in advance for your input.
