After some minor welding, I wanted to check the car’s level and dimensions again. I hung the doors, made a couple of jack stand adjustments, and everything looks pretty good.
I measured key dimensions and I am wondering how precise I need to be. I measured:
These measurements are essentially dead on. I think the inaccuracy is probably because of my measuring ability. I also measured between the hinge and door lock pillars (h). These are a little big. They are about 3/64 of an inch more than the factory dimensions, but they are the same on each side. With all the other dimensions being so accurate and the doors looking pretty good, I am wondering if I am being too worried about the precision of this. Or am I? Are these numbers pretty good for a car made in the 70s? Thanks, -Andrew |

Andrew, 3mm is the standard. 914's are particularly sensitive to welding stresses due to the design. Do yourself a favor and be sure you brace the chassis before continuing to weld. Rely on the lower set of measurements and less on the upper windshield measurements as you can simply push the frame and change the measurements by hand.
