I would be grateful of any advice reference fitting an 8P gearbox onto a 94 1.0 AAU bready. Firstly would I need to carry out any modifications to mounts etc or is this just a straight forward swap and can I use the stock driveshafts from the original box.I understand I will need a replacement  ARB due to the 5th gear but apart from that I’m unsure so any advice on this would be much appreciated! Many thanks. Rich.

late car so will have the correct arb 

 

you need the 5 speed mount with the box , id suggest you fit a new clutch kit at the same time and minimum of selector shaft seal and new oil ...or all seals if funds allow
