Cleaned it all up yesterday and gave it a lick of paint, so it's all looking smart now. Just got to get my old pump out the coupbard and clean it up before sending to Alex for the conversion

Servo, bracket and assorted gubbins won on ebay for £30. I think that's a result...Leave a comment:

Yup, common on Cabrios.
Thinking about it, to fit an ABY you will also need the bracket for the servo 8A0611945 and the bulkhead seal N 90125101. (These were standard on the B3 era cars but they dropped them on the ABY and changed the servo bolt arrangement to fix directly to the bulkhead).

Servo - 8A2 612 105 A
Try and get the rigid vacuum line with it, will make life easier.
I plumbing mine into the vacuum nipple on the underside of the inlet manifold that connects to the breather system on the ABY. I used an extra check valve to give double security against boosting the servo.


PAS pump - you can either do the ghetto mod and remove the pistons from the OE pump, or go custom
You need to cut out the bracket between the bulkhead and the turret. You also need to cut & weld the POS/plug bracket to clear the servo. Plug the fluid return line from the hydro servo to the rack return line with a bleed valve. Leave the hydro pressure switch plugs loose. I think that's it
