Price is right and quality is good. O-ring piston is machined .004 over OEM diameter and does not fit in master cylinder (a OEM 1981 FLH front brake master cylinder). Instead of returning it I just used the original piston with the new o-ring. To me it wasn’t worth the trouble returning it when I had an easy alternative. This kit also comes with a lid gasket but does not advertise it (so now I have a extra one because I bought one separately when I ordered the kit).
Peace out.
