Had a stripped pedal thread scare on a vintage steel frame

I was working on a 1980s Peugeot for a customer, and the left pedal crank arm threads were completely stripped out from a previous cross-threading job. I used a 9/16 inch helicoil kit from my toolbox to repair it, which worked but felt a bit sketchy on the old steel. Would you guys trust a helicoil repair for a pedal thread on a bike that gets regular road use, or is a full crank arm replacement the only safe fix?

Did you check the crank arm for hairline cracks yet?

Oh man, good call! Honestly, I had a crank arm snap clean off on a climb last year because I missed a tiny crack. Scared me half to death. Tbh I check mine with a bright light every few rides now, it's just not worth the risk. That failure really makes you paranoid about every little creak and click afterwards.
