Review on Moog K6607 Control Arm Bumper by Kaushik Sokolowski

Once installed, they're great. Put her on a 1987 Silverado. You are a nightmare to get ahead. Bad setup design. I've tried lube, boiling to soften, pressing, etc. I've seen a few people online drilling a hole on one side of the groove to help them get started, but since this is a restoration project I didn't want to smash my stock control arms. If there is a trick to getting them I would like to know. They are also tougher like poly than rubber.
