Guys am trying to locate part no.s and places to look for the a complete slipper setup for my cougar project. I presume i need a layshaft aswell

Ran in Caldicots vintage series on friday and was impressed with the car, just struggled a little on the slippy stuff with traction but i was running an 8.5 and lipos

Can also say it was wheelie machine on the carpet
anyways any help locating the parts would be appreciated.
I will post some pics when i get a chance
