I've been staring at the pic for no particular reason...
Just thought I'd mention a few things you may or may not be aware of (dont take it as offensive)
Your ac lines are bent in an interesting way (looks like they are more out of the way now) Maybe this was done when switching to 134a?
Your PCV hose to the crossover is routed a little strange, looks like it may catch on the ac pulley from this angle.
Whats the coil wire there tapped for? you have a tach or?
That ground for the IC pump relay is excessive, could be grounded right next to the relay on one of the other screws that go into the firewall.
Also behind the belt tensioner there it looks like part of the original IC lines are still in the truck? The bar obscuring the themostat housing looks like one of the original IC lines.
Looks like your also missing the pads that go around the hood supports, Does your hood shake a lot when driving?
You can trim a few zip ties there and put the cap back on the positive cable end too
Over all looks pretty clean, how many miles on the truck?
