Checking Frame Straightness
I'm just about ready to send my frame out for dipping, after which it will be welded and gusseted. Before I spend the money on doing this, I want to make sure the frame is straight. (There is some evidence of an accident on the passenger front wheel well) My question is this: What is the best way to do this? Should I take the frame to a shop and have it checked there? Is this something I can do well enough at home?
Thanks in advance!

Re: Checking Frame Straightness (75 BBC Stingray)
I had my 72 frame checked shortly after buying the car. The frame shop will sight in all the important set points and give you a print out of the findings. If anything needs a tweak, they can do it there. I don't recall the exact cost of the check, but I thought it was very resonable.

Re: Checking Frame Straightness (75 BBC Stingray)
I did this at home in the garage. The assembly manual show 4 points on the underside of the frame to measure from. I put the car up on jackstands, and used a pendulum type weight attached to a string as the pointer. Hold the string up to the mark on the frame, let the weight down until it touches the floor, and mark the point. Do this at all corners as shown in the assembly manual. Now measure the distance between all the marks, including the diagonals, and make sure they are exactly the same.
