This is a bit off topic. I am trying to locate some wheel cylinders to adapt to fit my 1937 Lancia Aprilia. The rear s2a & 3 seem to be 25.4mm (1") but I would like to know some other dimensions, if a member has an old one lying around could you please let me know:-
1 total length of the casting. Aprilia Lockheed ones are 79mm.
2 distance between the studs, center line, mine are 44mm.
3 center line of the bore to the flat face it mounts to the back plate, mine is about 23-24mm.

Many Thanks in advance for your time.
John

Just buy one they are cheep or find a landrover agent and ask him for a old one.
You could then try it for size.

I found a wheel cylinder and verniers...

This is a bit off topic. I am trying to locate some wheel cylinders to adapt to fit my 1937 Lancia Aprilia. The rear s2a & 3 seem to be 25.4mm (1") but I would like to know some other dimensions, if a member has an old one lying around could you please let me know:-

1 total length of the casting. Aprilia Lockheed ones are 79mm. - 76.2mm
2 distance between the studs, center line, mine are 44mm. - 40.6mm
3 center line of the bore to the flat face it mounts to the back plate, mine is about 23-24mm. - 25mm

Quite close, but not close enough. I measured a Britpart unit. Box says its a front cyclinder, but it is a rear cylinder (has two pistons)

Hope this helps
