Review on Beck Arnley 072 9799 Master Cylinder by Juan Mcallen

ordered this part a week before I needed it, delivery was ok even though the box was too small. I checked the fit of the parts before and after ordering to make sure I'm getting the right one. The part looked identical but during installation it was discovered that the fitting on the top end was 12mm x 1.00 threaded and the lines on the van were 10mm x 1.00 chuck. Just behind the port on the case is stamped 11/32 which should match the size of the hole. the old block and the block I received locally were not stamped at all. When filling out the return form, Amazon informed me that more than $5 was withheld from my refund because it's not my fault, well it's not my fault. They must issue a full refund and get their money back from their supplier. It is not my fault that the part is either improperly packaged or otherwise used. Beck Arnley supplies quality parts, I've used them for years but nothing is perfect. I canceled the trial membership so soon after and will think twice before ordering parts again. DISSATISFIED!
