Last min repairs before Thruxton - New Gearbox PLEASE!

So Paul and I had planned an evening trackday at Snetterton for Thursday evening with the aim of trying out some setup changes. Anti roll bar sweeps and damper changes mainly. We know snetterton well and have telemetry from the RGB Race back in May so the idea was really good. Now the last time I tested at snetterton was just before the season started and I managed to wreck the gearbox in spectacular fashion due, we think, in part to a failing fuel pump causing the engine to stall after a hard run down the straight.
"Stalling engine + trying to jump down lots of gears = crashed cogs" I think the saying goes!
Anyway we did some initial runs, changed the anti roll bars, went out and the car felt just about as I would expect it to. I went for an extreme setting, changing from the softest to hardest front setting and unsurprisingly this over stifferned the front and caused initial understeer. Once powering out of the corner it exaggerated the oversteer although I guess this is partially due to my frustration with the understeer and trying to get back on the throttle harder to make up the times.
Have I mentioned before I don't like understeer?

anyway my session was rather cut short when I came out of Corum into Russels behind other cars, caught a bad gear change and the car started to make clanking noises. Short crawl back to the pit garage and the car would not go into neutral despite the neutral light being on.

Long story short I had shot the retaining clip out again and crunched 4th gear quite successfully!
At this point, enter stage right, some amazingly helpful friends and family.

1. Andy, as always was amazingly helpful even on the end of the phone in the evening, offered to fit me in for a gearbox replacement first thing on the Friday morning if I could get the engine to him and do a turn around that day.
2. At short notice straight after the trackday on Thursday, John helped me take the engine out in a couple of hours. Not to shabby bearing in mind it has been 3 years since we have done that particular job!
3. Friday am, I took the engine down to Andy, and he turned it around by 2:30 which is amazing.
4. Dad then came around to help me put the engine back in and Tony arrived after work to help finish the job. We had a slight delay with having to take the engine back out because the prop had dropped down in our first attempt and then a little fiddle getting the coolant sorted meant a rather late leave to head down to Thruxton (9:30pm and 3+ hour drive) but the traffic was light and we managed a few hours sleep before the race meeting at least!
