Dan - What sill are you installing - did you buy the CCOT? What year and how's the build quality of the sill? Does it measure (gauge, etc.) up to the stock stuff you're replacing? Thanks for any info.I'm about to. Seriously. I was planning on cutting the spot welds tomorrow.
I've also got a new outer rocker to put on, and a new sill (along with a bit of floor repair).
It'd be great if anyone here has any tips or things to watch out for before I go about tearing it up with the plasma cutter.
The rear sill wasn't actually attached to the frame, but that was the worst of it. It was actually pretty rust free, but a bit banged up and bondo'd to look OK. I did a few patch panels, and realized how tweaked the quarters were, so new one's were ordered.How bad is your rust? What year truck will you be repairing?
I will be watching.
CCOT because they sold a complete sill. I'm kind of big on that for a little modification I have in mind. (stay tuned). I really like the idea of having the complete quarter panels, including the upper channels, so that there would be no seam welding, just spot welding. But since I was already ordering from CCOT, I figured I might as well get it all in one shipment.Dan - What sill are you installing - did you buy the CCOT?

They sell a Corner Channel piece for about $110 that addresses the curved portion.
But here's a real oddity to me. Maybe someone who has done this can chime in...

CCOT quarters. CCOT sill. Gap. If the sill weren't correct for the '79, I would think that maybe the earlier models or something had a different curve for the corners, but this is certainly a '79 sill. And the quarters seem to fit the tub on the truck just right... If it weren't for the flange on the bottom of the quarter, I think it'd be pretty easy to work the panel to the sill (but I haven't cut enough of the old quarters off yet to hold the sill up to them to see if the CCOT sill I got matches the original corners. Hopefully I can do that this afternoon.
Here it is from a slightly different angle, still showing that gap (1/2" or so!!)

I'm off to town to see if I can't buy some more or better spotweld cutters. The "premium" ones I got from Eastwood haven't been able to do more than maybe 15 spots each, and I've got a lot to drill out to get the quarters off. Should have bought the Blair, methinks. I'm hoping the local bodyshop will have some.
I'll post more on this tonight.
Corners not so much hacked, more like banged and bondoed. But the quarters seem to fit the current corners pretty well.Did the curve in the OEM sill meet the quarter panel through the whole curve?
I wouldn't know as mine had a PO hack job already done.
Thanks for all the pics and info.
I think you may need to buy the corner channels to make the curved portion of amby door opening.
As far as the rockers you could have cut your own and saved some dinero.
Oh well, it looks pretty darn good. Maybe all that shiny rust free metal is worth it.
Yeah. Typing this update is delaying me from getting back up to the shop to get any more done.updates?
