Since I've had no luck locating a radiator support for my '66, I've decided to buy one of the repops for the earlier trucks and do the modifications to make it fit. My question is, which mounting insulator kit will I need? The listing for 61-64 is different from the 65-66 models.
I don't have the answere to your question, but suggest talk to the people you buy the support from. They may have some information to help you on this. I don't know of any reason you can't use the later suport kit, and I suggest this would be the better support kit. I think the rubber donuts are a larger diameter and give more support and would have less fatigue.
