I remember someone who offered a fix for that, Hopefully they have something that works on the M rails, here is what I found in my search:
We offer the ORIGINAL slide rail repair option for the elongated, egg shaped, shock bracket mounting holes. Our kits are NOT a "band aid" repair - instead, they offer long lasting reinforced repair plates featuring built-in bushings, which will double the wear area around the damaged hole, while offering additional strength and durability to the rail.
The re-usable installation kit includes an aluminum drill jig, an arbored hole saw and nuts and bolts.
The repair kit comes with (2) aluminum plates, grade 5 bolts, a 3/8" o.d. stainless shaft and all hardware necessary to complete the repair.
We offer the following repair kits;
Upper Front Rail kits,
Lower Front Rail kits,
Upper Rear Swing Arm Limiter and
Lower Rear Swing Arm kits, for the ZR's, ZL's and FC's...
Note: Each Model requires it's own specific repair kit.
We are located in Central Wisconsin and offer same day shipping for any orders received by early afternoon. Quantity discounts available.
