And here is how severe it actually is. You can see the lean on the passenger side pillar, and on the driver’s side pillar it’s almost vertical.
And no that is not a distortion, the cab and cowl are sitting squarely on the sub rails. The windscreen pillars are really that twisted. The reason why none of this was visible when I first got the truck back was because the sunken cab hid the distortion and it was only when I took it all apart and rebuilt it that I first noticed the problem. And another thing I noticed was the diagonal strut on the passenger side was completely missing, so it would make sense that the passenger side would have sunk down even further than the driver’s side.
Knowing what’s caused the distortion will help me in figuring out how to correct it. The first thing I will be doing is bolting the cowl back into the chassis and repairing the toe boards and mounts, from there, I will place one of the legs from the chain block tripod frame on the inside of the passenger a Pillar and outside of driver b pillar at the top and place a chain around my tow bar and attempt to pull. The pole will force the passenger side one forward will it pushes the drivers side one rearward. That’s the theory at least.
Hey Guys. I took the cab apart to begin the repairs on the cowl. This included straightening the A pillar on the passenger side. I used a length of RHS that was clamped to it it. The idea being that I would be able to straighten it against the RHS using a large clamp. The only problem was the handle on the clamp kept slipping, so I settled on a better solution.
I ended up using the bench vice, the extra strength made it easier to straighten it. The other thing I concentrated on was the mount on the passenger side that had broken away.
With mount welded up, I wanted to see how much I’d managed to straighten the A pillars. So I got out the windscreen from the other truck and gave it a clean. And from there, I attempted to fit it. To my surprise the windscreen did fasten to the cowl, suggesting I had indeed straightened the lean. The only downside is there is still a lean from side to side.
You are getting there with ingenious out of the box ideas. A bench vise? Who would have thought of removing it from their bench to do that? I like your way of thinking. Kind of like a WV coal miner. Fix anything with baling wire and duct tape to keep production up and revenues coming.
