A couple quick 4 link questions

nice job!

Looks real nice,

beefy!!

looks good

looks real beefy but kinda long

The longer your links are the better of a pinion angle you get throughout the height range.

In theory, if you kept the upper and lower bars an even length, your pinion angle would not change. Being that the upper bars are triangulated making them "the same length" will be down to mathematical equations. If they were parallel that would be a different story. It looks like you have adjustable upper bars anyways, so you have some lee-way there. For the bridge, I used 1/4 C channel and it is more rigid than the stock crossmember (s-10). Mine also have holes in it (it was a tract lighting rail, haha) and they came in handy to mount my shocks.

My lower bars are 26 inches and the uppers are 29 1/2. I unthreaded the uppers 2 full turns so I have some room for adjustment if I ever need it.

nice! where did you get that kit or did you make it?

suicidedoors.com I was going to make my own but after pricing all the seperate parts it was just easier to buy one.
