Can you check my parts list and make sure I'm not missing anything?

Ok, so I'm about to place a pretty large order and just want someone to common sense check my parts list so I'm sure I'm not forgetting anything.

1st off...its a stock 69 c20, and the intent is to lower it and swap to power disc brakes up front.

Parts list:
C20 front power disc conversion, plus vac hose and plus braided steel brake lines(looks to have everything needed)
All 4 springs and shocks
Rear shock relocation kit
Adj pan hard bar for a c20
1inch block kit for the rear

All of that is coming from pol

I already have wheels, and am about to order tires as well(225/75r16)

Am I missing anything?? I can link to the parts being ordered if need be

The brake kit comes with 2.5 drop spindles. The front springs are 2inch lowering springs, front shocks for a 2 inch lowered truck. Rear springs are 6 inch lowering springs and the shocks the same. For a grand total of 4.5/6(or 7, depending on if I use the blocks or not)
