Poor quality. Inside sleeve is just a normal thickness tube cut to length. Not a thick sleeve with good fit for shoe adjusters to fit properly. Adjustment spring broke on 1st side I went to adjust. Set the other side up just so hub would fit and didn't try that side.
I have included pictures of the original parts from the truck that are of quality construction. The replacement parts are no where near a precision machined part.
I wish I took pictures of what I received. If you look at the pictures and read my comments about the sleeve being only a sawed off pipe you may understand my poor review.
My mechanic found that the end part that fits on the brake shoe was very loose not like the original part. He had me decide if I wanted to use them for the Datsun truck and because I would like to get it going again, I chose to have him install them. I hope they work?
My truck actually came (private sale) without one of the adjusters on the back brakes and the other one on the wrong side! These are great quality for a fair price. Fixed my truck right up!
