All right...I've now that I've got a little time, I'll explain what's been happening lately on the '64. In my recent postings, I attached pictures of it at ride height, and although I was jazzed about the way it looked, the control arm clearance to the ground was about 1 3/4", and that just wasn't going to fly. I did a lot of research on Dropmembers, Z'ing frames, and sectioning crossmembers, and although each one had it pros/cons, I just needed a nudge to push me in that direction. Enter Kustombrad and Bob......
I've known Brad since I was a G.I. in the Air Force back in the late '80s, and we've always thought alike when it comes to cars. Between us, we've had quite a few cool rides. For the last 20 years, Brad has always talked about wanting to "Z" a chassis on a '73-'87 truck. Once he saw how low the control arms were on my '64, he was on a mission........he was going to do his best to convince me that Z'ing the chassis on my '64 was the way to go. It took a little bit of convincing, because I wanted to carefully plan the job, but Brad already had the cutoff wheel spinning in his brain. Once I said Yes, it was headed over to Bob's house.
A little about Bob.......he's about 60yrs old with the drive and passion of an 18yr old. He is an extremely talented metal man, and has chopped more tops than I can care to count. Nothing scares him, and he was 100% ready to do the job.
Anyway, as soon as the truck was in the shop, it was carefully leveled and measured. The frame was jigged at ride height in front of and behind the crossmember.
The area directly under the crossmember was also jigged.
It was determined that the frame would be Z'd 2" up higher, and forward 1" to center the wheel in the wheel opening. Once the jigs were in place, they determined where the best place to cut the frame would be. In the rear, the frame makes an inward taper, so you have to take that into account. Also, you want to ensure that you cut behind the upper shock stud. You want every bit of the crossmember, including steering and shocks to move up as a complete assembly.
The front cuts have to be carefully planned out, because you have a few things to concern yourself with. First, the steering box. Everything in the steering box area starts to get tight, namely the radiator. You have to plan your cut where it's just forward of the steering box and just aft of the radiator saddles.
In this shot, you can see how close the radiator is. You still have good clearance because the radiator is secured on the top and bottom.
