Looks like we'll save the Junker Klunker!
Spoke with the neighbor welder again and he said without having to cut the lower arm off we can just cut some
thick steel pipe like water pipe ? lol
Then cut a groove out slip it over the lower arm, leaving the chewed area exposed, lol
and weld a full bead line along the pipe and lower arm.
He says even if the chain chews through, it will not compromise the structural integrity of the lower frame arm.
Wish me Luck!
