No worries Mike

I will be certainly adding as much info as possible and by the end I really hope it'll be a full guide to the job...
You have the ideal donors there and it'll be a lovely project. The one thing you need to get is a V6 gearbox... Luckily the same vendor I bought mine from
has another. He got mine to me in less than 24 hours...
Then get a manual clutch and flywheel and off you go... Those are best got from a specialist Pug 406V6 breaker. There's one in Chesterfield whose name now escapes me except the old boy who runs it is known as Ade..
You're right about the prep being the worst part

I'm so relieved that phase is now over. I'll be even happier when the remains of the donor is gone too...
