Thanks for the reply, man it's HOT here in Tx. also! Moving the shaft over a bit with a u-joint and heim is not a big deal if it will allow these big tube headers to otherwise fit the chassis. I hope thats the only close spot and I'll be in good shape. I built a race 71 240 years ago and rememeber doing this to that shaft as well. Just now cant remember where I got the universal joint, it mic's out metric in between 9/16" and 5/8". If I could find a 9/16" joint I'd just finish drilling it out to be a interferance fit and weld it up, this would really help keep it running true. Im also doing a 383/glide setup and really looking forward to getting some track time again soon. I had just enough room for 28x 11.5x 15 from my first tub job nearly 20 years ago, I cut them out yesterday and now have 20 inches in the clear on both sides, lol. I'll prob. end up getting a set of 32x14 but could go 32x17x15, sucker would look like a steam roller. thanks again.
