On the bottom there should be no washers used so the feet stick past a hair further
on the end up rights there should be nuts and washers locking it down.
I know they were not on in the pics but that was because I was just tryiong tio give you and idea
Every deck should be locked in place on both sides and the underneath tof the bottom does not get washers
the rods shopuld be flush with the nuts on the under carrage and the space for the first deck should be measured to fit a power supply upright and tighteened down til it is snug ....
I personally use the little 3/8" round clear rubber dots at Home Depot in the feet section on the PS so it does not scratch the paint
if the 1 1/4" screws did not get tight grad 6 1 5/8" screws to replace
then all you should need is the rad mounting screws & the top deck is on upside down ............. LOL
Looks great BTW.................
