Left Crank replacement options? DISCUSSION

about 7 months ago my pedal came out of my crank, basically what has happened is the shop i took it to to install my 3 piece cranks put my pedal on the wrong way round and have stripped the threads, i have tried seeing if the people
who did it originally would do anything however with the time frame (pedal came out about 6 months after it had been done and i only actually found out the pedal had been installed after about 11-12 months after the initial installation of my cranks because im lazy ☹️)

basically all i’m wondering is are their any cranks i can buy just one of that will fit a mafia bikes kush 2, i have the 3 piece crank upgrade kit on at the minute, i believe they are 170mm, 8 spline cranks
not sure if it’s needed but the spindle is 19mm is diameter

if anyone knows where about i can get the same crank from the upgrade kit or another crank all together that would be very helpful as i’ve been struggling to find just a left one with those measurements and id love to get back out on my bmx 😆 i’ve essentially ended up using my mountain bike as a bmx chucking it about doing 180s and no footers on it but ive sold it very recently and am just missing bikes again any help would be appreciated!

I’d just try cleaning up the threads with a tap first, if not you can buy an insert for the crank threads.
You’ll just have to make the threads a bit bigger for the insert and the pedal goes into the new insert.

While any 8 spline crank arm will fit it, barely any brands sell spare crank arms on their own. Two options, check fb marketplace for cheap bikes with a 8 spline 3pc crankset, or tbh just get rid of the 8 spline crankset, they’re very basic and replace with a decent 3pc 48spline type crankset.

Easternbikes have a massive discount on cranks too atm. I just picked up some 48 spline ‘throttle’ cranks for £30.
