anyone have Comp Eng. frame connectors?

I have a 71 340 duster and comp. eng. sub connectors. My car is on the rotiseri right now
but I didn't like the connectors. You will also have trouble with the E-brake cables. You will need to find another way to mount them also. Comp eng. dropped the ball on these as far as I'm concerned. I do like Jo D's 2x3 suggestion and will probably try that myself when the weather gets warm again.
