Am I missing something? I bought a 69 K5 blazer and tore into it. Tackled all the rust, A pillar,B pillar, replaced and repaired the windshield frame, repaired the rear floor reinforcement panels.
I've did several searches on here and read many build threads. But have yet to find anything referring to the process of correct rockerbox installation.
I'm priming the bottom of the floorboard and the complete tortion boxes with epoxy primer before I install them.Afterwards I'm doing a spray in bed liner over it. I cant find on here anyone sharing there install of there tortion boxes. Is there any order into which is the best way to install? Just don't want to put the cart before the horse,,,,,
? would you drill holes in the front lip of the TB and weld to the lip on the firewall. ? should the TB be flush along the inner rocker/outter floorboard alone the bottom.
? Leave TB cap off until the TB itself is welded in, then install the TB cap or bolt in RB cap but leave lose then weld in the RB.
Have I missed this on here or is this a good valid ?
Thanks guy's, I know the answer's are soon to come.....

The rocker boxes keep the body from sagging when the top is off.
If I were to install rocker boxes I would have the top on and the door gaps set. You will need to install the rear pieces of the rb that bolt on first and then weld the rest in place. If you were to weld the main rb on first and then moved to the rear portions it's likely the bolts wouldn't line up since there are just so many bolts and variables.

You may need to trim under the rocker panel for it to fit. I am not sure what you mean by drilling holes in the front of the box, originally it was just a couple weld beads on the front lip. If these are reproduction pieces don't be surprised if things don't line up perfectly.

Thank you 69-72 for that imput, I would also like to the think Ebfabman also, I just spoke with him and he gave me a ton of info for the install of tortion boxes. He has been a lot of help also with my build, I just couldn't get a hold of him yesterday and got alittle antsey.....
