They were OE.I was only going to do the uppers but I decided to do all 4.Being on the rack at work and my SnapOn air chisel helped.That and I did a ton of chassis work at the shop.You learn a lot of tricks after over 30 years of doing it everyday.I did screw up on one lower.I didnt have the snap ring positioned right.Took me about abother 20 minutes to get it straightned out after I had it together.Rocky
