Apologies! Just re read you post! I think it could've been a road frame built as MTB. The thread is here https://www.retrobike.co.uk/threads/dave-russell-531.432402/
I don’t suppose you fancy selling both the cracked crank arms do you? I’m trying to claw some money back on something I brought that ended up being toast as a wall hanger
Finally got round to digging this out, it measures about 180mm in total with just over 60mm of thread. It's a genuine Pace item & is complete with the C clip at the base.
I'll sling my hat in the ring this month,
Mr Ox's 1990 Dave Yates Vulcan

Ah the irony! I’ve just purchased a threadless steerer!
I have a couple I’d be happy to swap for threadless as it might save me cutting the new one down. What length do you need & what length is your threadless?
