Yep. Ive been down that road before too. I have several UN1 boxes in the workshop and decided to check out an NG3 that was in the later Renault 20 cars. It sure is a smaller gearbox, the crownwheel not much bigger than a tea saucer. They do have a 4-spider diff unit, but even that is soo tiny. I think that one planting of the boot with a V8 on it will shred every tooth in 1 fell swoop. Not to mention twisting the shafts like a peice of liquorice.
Now about that UN1 you have there ....... what do you think its worth to you?
