I would be happy to build a few gearboxes but time is very short, spend most of my time watching CBBCs and going walking / stomping in woods with my 4 year old - he loves being out side.
I have 1 new one to build and about 3 old ones in bits.
Also got an axle to rebuild or recon.
Remember I did my own gearbox which is the first one I had every touched, and I know what went in to it and got the result I wanted

They are not hard to do but take your time and think about each step.
Time is very valuable.
This weekends jobs are refurbishing my front door seals to make them plump again and fitting a CTEX comfort lead and extension so I can keep the battery tip top over winter while car is covered over
I think it is good that the marina is getting a better deal on price. Gavin's TC coupe should have gone higher. Mine will only get a good price if I set it on fire then the insurance will pay out. Not planing on doing that so don't worry.
