    hopefully this is off topic enough to be in the lounge, had my frame shortened a few weeks back and I've got a welder coming this weekend to plate the frame, weld in a new xmember, and new body mounts (those are going to be fun, both width of frame and body mount holes are exactly 38")

    Well we planned to step-cut or 'Z' cut the frame but we had to take too much out and it wouldn't have worked out so we had to do a 45 cut, even with a 45 cut we could not have taken another inch out.. nevertheless with the cut and all that's going on in this area I'm confused how to place it properly. Frame height is 8" so I'm kind of leaning towards a 6" round plate. What are your thoughts? Id rather plate the inside since the frame will be pretty visible but I'm not really seeing how that's possible either.

    I would grind out where the bracket was cut off (shortest one) and weld in a 1/4" diamond over the center of the cut. If you can, reinforce under or over top cut. Probably stress crack there first if it is gonna.

    If this guy can get that brace out we will definitely go under, you don't agree with the circle plates? I thought diamond plates were more for a step/ z cut due to being able to cover the entire horizontal seam/ weld?

    You do not have to cover the whole weld/seam. 1/4" thick Diamond will spread the stress. Your weld looks good from here.

    I'm sure we can whip up some diamonds but what's wrong with circle plates? I already had the guy thats going to finish this cut them in 5 gauge to match the frames thickness.

    Right on thanks for the confidence boost, I knew it looked pretty good but I'm never sure how good.. even the frame job I wasnt super confident about knew it looked pretty good. Welded some strap on the top frame rail at the splice.. body is setting on it because i still need to fine tune positioning and drill holes through the new body mounts so there's no bushing in there right now.
