It’s a thing of beauty, Nick you’re doing the Lord’s work.

I saw this as a unique opportunity to mate the best gearbox with the best engine.
I started off with great ambition, but gradually slowed down, and now I'm not making any progress, I'm afraid.

Same, I actually sold the car I was working on. One of the biggest ?’s was the gearbox tbh and part of the reason I dropped the project was I needed a high enough revving transmission and it wasn’t feasible to have one custom made not for a car worth less 10k. (At the time probably less than 5k now). Well I’ll work on my oil situation for now and consider the project feasibility. Good luck! I hope something comes about that sheds new light on the project. If I happen across anything that might help I’ll be sure to let you know.
