Cool. This is what mine look like today. I added a triangular brace to the back of the square tune for additional strength. I also tapped the other ends of the tubes today.  Rod ends I bought locally: 
Drag Week 2011 - 77th place - DD
Drag Week 2012 - 2nd place SRBB N/A
Drag Week 2014 - Kapooya
RMRW 2018
RMRW 2020

I made a set for my wreck. Make SURE you get some good shocks too. I tryed mine out at the track with the old set of stock shocks I'd been running with my pinion snubber. I'm lucky I'm still here to type this. I've since bought and installed a set of Rancho 9000's from Calverts racing.Dave 
i understand the need for a good shock, but could you elaborate on the behavior of your truck before the shock change ?

The old shocks topped out at the hit of the throttle. It spin, slid, and porpoised the entire length of the track. Without some control on the extension or compression of the shocks, you'll see zero weight transfer to the rear. I spent my whole time during each pass just trying to keep it off the rail and trying to keep it semi-straight. I tryed 5 passes that day, made it to the end under full power 3 times. I should have aborted those 3 also, I was a danger on the track. Dave

Just to shorten up my situation, my body bumpers that are mounted to the bed support frame/cross member are bottoming out on the topside of the axle housing. I have maybe 3/4" clearance between them and the shocks are nearly compressed with it sitting idle on the garage floor.. Make sure you look at that too.
When you decide to quit, THAT is the moment when you would've succeeded..

i thought the shock being too short would be a problem.glad you kept it shiney side up ! how much longer shocks did you end up with ? also, how stiff on extension did you go ?

Looking great... Did you take the bushings out to replace them, or are you putting solid aluminum inserts in them or what?
