Re: 70 C10 SWB Frame Measurement Needed
Thanks for the drawings Problem is, I still have the cab on the frame, I only removed the bed, so I don't have easy access to any of the gauge holes. On top of that, it's sitting in a driveway that isn't level.
I also don't have a reference hole by the bellhousing crossmember. If I'm reading the 1st drawing correctly, it should be 2.78" from the center of the crossmember, and there's nothing there. Looking at another thread, seems someone else had to slot the holes as well, so I think I'll bolt the front in and just slot the rear piece as needed. https://67-72chevytrucks.com/vboard/...d.php?t=837552 |

My frame was SWB to start with and the rear cross member rivet holes are where I started. I figured they were oriented correctly and square to the frame rails, as they seemed to be, because they lined up perfectly. All the slots I put in were in the front frame brackets.

Good luck with it, the brace seems to really stiffen the frame.

If your surface isn't flat and level you need to shim your frame supports (jack stands) to get the frame level. Using a cheap 360 degree Lazer level and a tape measure can get you with in the 1/8 of level needed for most vehicles. Once again if you've already done this please accept my apology. I've seen to many cars marginalized by poorly installed subframe connectors and/or roll bars.

Re: 70 C10 SWB Frame Measurement Needed
You would think it would be, but 10 or 12 years ago we had a guy bring a nice mid 70's Camaro into the body shop to get his doors aligned. They were hard to open and you had to really slam them to get them to shut. We assumed they would need new bushings in the hinges but, after inspection we found the hinges were nice and tight. So we looked further thinking the car had been wrecked or something similar. The only thing I found was a set of frame connectors that looked newly installed.
After some discussion with the boss, he called the owner in and, after some more discussion, the owner admitted he had installed the connectors a couple months earlier. When asked how he installed the connectors he said he just jacked the car as high as possible on one side and welded that connector on before moving to the other side. He claimed not to own any jack stands just a floor jack. Fortunately for him his welds were poor and not nearly enough so it only took me 3 hours to remove them and grind everything clean. Then he paid us to install them a second time.

I had the rear higher so I had room to work and get everything in, but I moved the jack stands to where the axle would be to try and simulate where the weight would be and levelled it out front to rear best I could before tightening all the bolts. |
