son of a.... i was searching for "flanges"...
got it "done". a couple small exhaust leaks where i welded, mainly cause i can't get to the top of the pipes to get them. it will most likely make a bit of a rattle, cause it's way too close to the frame to not hit it. hopefully that will motivate me to fix it sooner
i was two clamps short, so i'll get those tomorrow.
also got 3 of the frame braces for the new slider welded on. got to make the fourth. the p.o. didn't put anything on to distribute the impact and it's kind of hard to see in photos, but your frame will bend.
