Jamie,
I talked to you before when you wanted to wait for PCM to test his. I have access to my 73-87 AND I have access to a 67-72, both with LS powerplants. I don't mind cutting them up if I am covered.

I can say that I tried ECE mounts on the 73-87, you DO NOT want to do this, It will force you to move your whole drivetrain forward, causing you to have to move the crossmember and get a longer driveshaft.... Look at this post for a comparison of the ECE over 3" forward, vs the plates. http://67-72chevytrucks.com/vboard/s...8&postcount=38

I also have access to 1" back mounts and I can swap them out and see if I can mod the headers to fit that setup on a 73-87, that way it would cover all mounts. More people will be inclined to move it back than forward in my opinion..
