Super easy repair - I didn't want to wait for the dealer.... if you want to tackle it on your own, takes 5 mins max. You just need to remove the plastic seat backing.
1) reach under and unhook the elastic hooks and flip the flap up
2) remove 2 screws that are now exposed
3) slide plastic...
Don't have a part number but this is the specs for the Overtrail Wheels
18x7.5 +50 offset
Center Bore / Hub Bore: 95.1 mm
Bolt Pattern: 6x139.7
Wheel Fasteners: Lug nuts
Thread Size: M14 x 1.5
Looks great!! Looking at doing the 18x8 +20 with 34's on mine. Where did you pick up the TE's? I called a couple vendors and they are saying 8+ month wait.
