Aaron - I am glad I am not the only gearhead who was surprised at the relative difficulty of the 3.2 cap attachment. In time doubtless I'll get better at it. One of the guys whose cams we checked at Sebring didn't know how to remove a valve cover, but happily was fine with removing, and more importantly, putting back on, his distributor cap when we were done.
Another thing I left out: The 3.2 caps use a post, not a hole. Other than not being able to use 3.0 and earlier plug wires, I suppose it isn't an issue. Is the post a firmer attachment? The coil packs I have on my modified car with crank fire have posts like that. Did the whole, or most of the automotive industry, decide to change from negative to positive or whatnot?
It certainly was harder to drill out axially than the 3.0 cap when making an adapter for measuring cam rotation!
Apologies for the fuzzy focus on the middle picture.
