Installation Notes:
Plastic isolators are used between the steel brackets and the aluminum body. There are two sizes of isolators: large diameter (10mm) and small diameter (8mm). Separate these ahead of time to avoid using the large isolators on the small bolts.

Installation Instructions:

1. Install large diameter isolators on 10mm mounted studs.
