Little update here.
So, earlier i said i thought the car was fixed, how wrong was I

. I had our mechanic fit a new clutch, as the old one was ruined due to oil contamination, and he put the new (secondhand) gearbox back on. It then sat in the garage for a few weeks while I was at uni. Got back from university on wednesday and couldn't wait to see if it was all ok.
Opened the garage up and took it down the road for a drive, and behold, the differential on this supposedly decent gearbox was whining terribly. Oh dear. But as least now I have a decent casing for the box to be rebuilt in. I'm back at work now so money isn't as much of an issue as when I was at uni, so this is the plan now.
Waiting for a group buy on Quaife ATB diffs to be sorted out and should have one ordered by the end of june. While this is being sorted out I'm going to get the gearbox rebuilt with fresh oil seals, uprated bearings and new synchro's for the first three gears.
I'm now borrowing my brothers punto off him to drive while my car is out of action. I hate driving it compared to the 106, its so wallowy and has no steering feel whatsoever but I'll have to make do. I'm also considering maybe buying it off him to keep as a daily, and then I can really spend some time and money on the 106, and sort it out good and proper
Anyway thats about it for now, will update this a bit more when the gearbox is finally sorted!
Thanks, Tom.
