My 60' Galaxie with 72' 460 currently has log type passenger car manifolds. I would like to know if anyone with this combo has tried to install or is using PI/CJ Manifolds. Have a lead on some 73' PI's and don't want to buy if they don't fit, as manifolds are located out of state. The price is $400.00 dollars and are said to be in excellent condition with no rust or pitting. Is this a good price? I understand that there are factors such as motor mounts and engine placement that will effect that installation. I thank you all in advance for your time
