1973 Barracuda front bumper mounting question

[ff6849]

I having trouble remembering how the front bumper goes back on, I have the brackets installed the ones that look like a Y coming off the frame, and of course I don't know where the bumper bolts are.  There is heavy piece of steel that attaches to brackets and the chrome bumper goes over that. What I am not sure of what bolts I need to attach everything, and the order in which they are done. Does anyone have a schematic of the reassembly and what size bolts and how many bolts I need, and by the way this 1973 Barracuda.   First project and disassembly was aways back and didn't do it in very organized way either.

My 73 Challenger uses (4) roughly 1 1/4" stainess capped carriage bolts through the bumper into the larger reinforcement.  The rest of the fasteners are the same length but are just regular bolts with captive washers.  The nuts on the back side are generic but the loose washers have teeth on the back side.

I have no idea if Cuda bumper attachment is similar or not.  Here's a pic of a 73 Challenger bumper if that helps at all.
