Hi, does anyone know where to measure from when working out the length of a prop. The lengths given in the wiki don't specify, i.e stud end to stud end or input face to the flat of the uj ?

Just trying to work out which prop I have actually been sold.

Thanks,
Nick.

You need to take 2 measurements.
1st is the full length from the diff to the guibo on the back of the gearbox.
2nd is the the length from the back of the gearbox to the centre bearing, and from the centre bearing to the diff input flange.

Thanks Rav
