Mid Plate Install
Posted: Thu Jul 21, 2016 8:04 am
I'm installing a mid plate between the SBO and TH350 in my '72 Cutlass. No big deal only runs 11s but I wanted it to be easier to remove the tranny or engine without have to remove both all the time. I already run a front plate (3/8" aluminum) and limiters on both sides, plus an ultrabell on the tranny.
Anyways, I am welding 0.125" 1018 steel to the stock frame rails for the mounts and was just looking for guidance. I was going to TIG them in using ER70S2 but I can't get a good gauge on the thickness of the frame metal. I'm been told it is 3/32" (0.093") but it seems thicker in some areas; maybe it is just built up paint and grime. Any idea where I should start for juice? I was going to just start at 125A on the dial and then back it off with the pedal if I needed to. Also, should I look at -6 rod since the frame is pretty old and I'm guessing prep won't be the best (it is hard to get into the area with my flap wheel).
Thanks.
