The pull crank that attaches to my A pedal rod broke on a gig the other night. The welding gave way where it attaches to the cross shaft. Mid 70's Sho Bud. I've never had anything re-welded before (or first time welded for that matter!). Is this even advisable or should I be trying to source a replacement (or upgraded) part? On the one hand I'd like to keep the guitar as original as possible but it seems like a weak point in the design. Any advice much appreciated.
Borrowed pic from the internet shows the welded pull on the left:

PS fair price paid if you have one of these lying in your spares box!
All the best
