Thanks, Imp. I'm hoping to avoid replacing the subframe, at least for the moment.
If I go that far, I'll want to do a lot more. Not time or facilities at present to get deep.
I think the rest is in good or at least better shape than this trouble spot. No apparent signs of deep rust.
May have to lower it to weld, maybe not.
How many attachment points for the subframe to body/engine?
Two are plainly visible at the rear.
Is there a thread on this - I've searched but not found yet.
