I did a bunch of measuring & ciphering before I ordered the cold case. It is thicker than a stock radiator, so if you have the 70 & up aluminum water pump, there isn’t much room left. Not so much of an issue with the 69 & back water pump as it is about an inch shorter.
I never used the jag clutch as I read that it wasn’t a heavy duty design. The 2947 fits fine but it is a pain to install as there isn’t much clearance for the water pump bolts.
