Plenty of room. I have OCD so usually document things, luckily this is one such instance.

There's stacks of room and no issues mounting it (use industrial strength resin style glue to attach the Raptor mount). The hole itself which the Raptor pokes out of in the front takes most of what little weight the Raptor has. The Raptor bracket is there just to help (if anything). My RH pillar is custom made from plastic and fiberglass (due to the RHD conversion) but it still appears to be the same dimensions. It's easy enough to undo 2 bolts and unclip it to check space anyhow.

Once again, this is an older image prior to painting the interior black.
