Finished doing a quick wire brush of chassis to check it over, discovered another spot that needs repair on drivers side of frame lower part near the gusset where the braces bolt to the chassis, there was quite a lot of critter debris in this area.
Started fabricating repair pieces for T-section.....using 14 gauge, amazing how much thicker another .014" of material looks!
Still need to cut the lower vertical part of T-section off ....I think I am going to remove 2-3/8" which will bring it the internal box shaped gussets.
