upright measurement

[gib6933]

Hi just a quick question im trying to measure my rear uprights, I have a feeling they are 4.25" PCD but I want to make doubly sure and I don’t know where to take the measurement from?
Can anyone help me out please and point me in the right direction?

No problem.
Just remember you need the measurment of the stud spacing e.g. to measure to the middle of the studs.
Easiest way to do this is to use a vernier calliper to measure the stud distance outside edge to outside edge (if than makes sense) and then subtract the measured diameter of one stud.
