Had a bit more progress with this today. Managed to pull the old K50 gearbox out and get the K-T Bellhousing on a T50 I have so i can start to get the gearbox mount sorted out..
Problem I ran in to was the gearbox to engine bolts are around 20mm too short, Sucked to find that out once I handled the gearbox up in to position... So looks like I am doing a bit of bolt shopping next week.
