My 66 Chevelle P/T build

[MMcMasters]

I got back to work this weekend. Saturday morning I thought I would media blast the open channels on the frame "real quick". That turned into 4 hours of dealing with clogging due to my POS harbor freight pot blaster. I finally got it done though.

I'm following the ABC performance playbook for the rest of the frame mods. First thing I needed to do was make 6 adjustable legs that I can weld to the frame to allow me to get it to a workable level and square/ level everything up.



Once I had all 6 legs welded on and gusseted, I leveled the frame front to back and side to side. I used 1/4" strap in the rear, 1" tubing at the c notch and I welded in 2" angle across the center of the frame rail to keeps things in place once I start cutting. The center body mounts should be 53" center to center. I got lucky I guess because mine were dead on.



After dealing with the frame sag issue last week, I wanted a little extra piece of mind so I made a brace to put between the upper control arm mounts.



The bottom of my center frame rails were pretty bent up from years of use and probably from being used as a jacking point. I took a piece of 2x2 square steel and cut a slot in it so I could use it as a lever to bend the rails back up into shape and fit the boxing plates. ABC's laser cut plates fit very well and needed only minimal trimming on one end. I got both sides tacked in a few hours.



The rest of the afternoon today I spent welding them in for good. I was patient and took a great deal of time welding them up to minimize heat and distortion. I used 2" stitch welds and moved around a lot. Once I was done I dressed all of the welds and gave them a nice radius. I am very happy with the results but not very happy it took me a whole weekend to get this done.
