I didn't have a bearing puller lol, so what I did was....
Insert a long bolt in the centre of spigot with the head to the side then jammed another bolt in there to keep the 1st one over to the side to grip the bearing,
Then put a big washer on the long bolt,
Then a nut on the long bolt and then tighten the nut and this pulls the bearing towards you!

The big washer is to sit over the hole the bearing sits in if you get me??... So when you tighten the nut the big washer grips against the hole and pulls the head inside the spigot toward you (thus pulling the bearing) out

Its hard to explain, I hope you can understand my method lol, I made it up on the spot at the time as I tried packing it with grease and using a drift but I had nothing that was a snug enough fit so that didn't work for me. I then came up with the above and hey presto :D 8)

ive just routed my ecu (m50) under the dash but the loooms a bit short and it sits on the pee. did you have to extend every wire on the ecu loom or just those pictured when the loom is plucked apart? other than that i need to sort out an issue with the clutch slave , finish the exhaust and fan loom and im ready to roll winkeye

only a few wires need extending, it will be obvious to you which ones do need adjusting.

piece of advise mate, cut 1 , extend it then move on to the next. they didnt need extending much but my ecu sat right once i was finished :)
