I need to replace the fuel sending unit in my 1967 326 with air conditioning. I need to source the part myself as the shop I'm using cannot find the part. I need the unit with the vapor return.

First of all it appears that these are hard to find and when you can find them their prices vary. I found one at the Paddock for around $50 and I have seen them other places for $115 - $130 and the GM ones are over $200.

Does anybody have an opinion on these? Would I be ok with the one at the Paddock? Also are they the same ones that were used on the camaros?
