John Greenslade Posted November 7, 2001 Share Posted November 7, 2001 I have now spot welded floor pans and front frame rails in place on my 70 240z. I tried to measure the frame rail cross dimensions from the factory manual to check that rails were square and that front cross member was in right place but didn't have any success (i'm a novice at this so maybe I was doing incorrectly). I left part of the passenger side rail in place as a guide and on drivers side welded to the exact spot the original rail was cut out of. My main concern is on the passenger side rail that the stabilizer bar and the cross member are square to the driver side rail. Does anyone know what a reasonable margin of error is. I.e. if everything is within a 1/4" is that adequate. I am thinking of having towed to a frame shop to double check before I weld the rails to the inner fender. Any comments.

Guest JAMIE T Posted November 7, 2001 Share Posted November 7, 2001 I think the book, Chassis Builders Handbook, states that @1/8" is ok. It says, thats what suspension is for. Jamie Quote Link to comment Share on other sites More sharing options...
