74 Five MPH Front Bumper & Shocks

Thanks, good info. I got lucky setting it up as I had some some 2" angle with 1/2" holes punched every 2.5" on both sides. I cut them in even lengths and using the bumper bolts attached them to the bumper which with the plates and channels attached it turned out to be the perfect width to mount directly to the frame. I don't recall there being additional tapped holes for bolts but there were punched holes on the outside which I had to drill through in order to mount my "contraption".
I'm almost thinking of doing the same thing on the back with the stock 74 bumper as it's nicer than the 72 I'm planning to use.
