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.................
