Well here's another update for those who follow this thread
I had it real close to driving, but needed something to drive since I hadn't had anything to drive for about 4 or more months, so I took a break from the GMC and put my Honda back together, long story short I'm selling the Honda and have gotten my truck back on the road, it still needs work, but is getting me from place to place
I'll have to take some more recent pics, but here are some that will update yall a lil

Swapped my plastic clutch master and slave for some 90 1ton cast iron ones, and built a Stainless braided Teflon lined hose with Banjo fittings (note, this works but you must you the longer rod from the previous slave cylinder and it pushed my clutch pedal way up, so I'll be having to cut it down)
And I got my exhaust installed, true dual 3" with single chamber CherryBomb Extremes
