[adammay 0]

Hi lads ive got a 1989 205 with a 4 speed gearbox but want 5 gears!! Is it possible to get a 5 speed box of a pug 106 1.1 thats sitting at my local scrappy? Would it be straight swap? Thanks

What year is the 106? IIRC they started using a thicker pin through the planetary gears in the diff at some point in the MA boxes so your driveshaft inner ends might be too long and foul the pin. This means that you may need to set the driveshaft oil seals a bit proud so that they will still seal.

 

I've heard that the fouling of the shaft ends on the pin can cause failure of the diff but I don't know how common that is.

 

Other than that is should be a straight swap.

 

Hope that helps.
