    5 speed propshaft to 6 speed gearbox

    Is it just easier to source a 6 speed unit? Or is there a simple mod??

    Assume your ditching the spacer and using a single mass.
    I used the front half of an Avant prop.

        need more info.

        but for a CQ/S2, going from an 01A to an 01E and the trans stays in the original location, you need to use a 4kQ propshaft. it is the ~1" shorter to make up for the longer trans. unless you want to push the rear diff back on the subframe that same amount, that would work as well.

          I have an ABY coupe prop here I can swap with you if you want Tom - I was going to shorten it anyway to use with my other 0A3 gearbox
          It needs CVs as the old ones were shot, but you can just take your old ones off yours and go with them, or I can give you the Lobro p/n for new ones.

          Just cover the cost of post

            Mate, there's a place in Bristol that will shorten your existing prop and rebalance for just over £100. I'm getting mine done there. Do you still have the same mobile number? PM me if not and i'll call you.

              Tom, if you’re using your 3B front subframe you’ll need a spacer for the gearbox mount.

                I need to get one made for my 6-speed conversion. I've seen various sizes being mentioned 35mm / 38mm?

                  I found different sizes quoted when using a 7a front subframe on my Aby- varying from 30 to 40 mm, ended up with a 37mm one fitted with no probs.
                  I have a spare one I can send you if you like

                        I can knock you guys up a 37mm spacer if you need, did one recently for RXL with his gearbox swap kit

                          Do you just make a spacer to sit on top of the mount or space the mount on the subframe?

                              A made a lot of spacer investigations for my V8 cause it doesn’t have one, so far I understood the spacer story it’s dependent from the flywheel you will use.
                              It’s about the height of the flywheel and clutch - I think around 80mm was the limit for the clutch pedal and the reason for the difference is where your trigger wheel and sensor are located.
                              May this helps you
