Mounting RCM battery trays

[rootar]

yea my my rcm rc8t is ues 4 m4 screws, and trust me you could land it upside down from 3 stories and that tray would still b on there, i dunno about the rest of the truck but the tray would be, now in my xray its overkill, i have 5 screws in it, (2)m5 nitro motormount screws, (2) m4 screws i drilled and countersunk, and i used one existing m3 screw from a radio tray mount..... just do like mike said under size the holes and screw them in you dont need to do anything else.
