Can someone tell me what body post mounts I am going to need? I am converting a K6 EXB to a Kraton XL with a Mojave EXB body. I see 2 packages for body post mounts. I know I need a total of 8 but one of the packs, #ARA320545, only comes with 4 and #AR320365 only comes with 6... the math doesn't make sense.
