New to me, but I have a used wfb31 with white/allied loader, tilt cylinder on loader is leaking through seal.

Two questions:

I can not find any part numbers on cylinders although there is an identifying plate on loader itself ( reads 11550a - 36312). Any info would be very much appreciated.

Also I have now noticed that left and right tilt cylinders are different lengths . Should they not be same cylinders?

Thx,
