Since the gap was even all the way around, we cut our perch on a chop saw to be more accurate, and then built the perch on the workbench. Looks like I have some clearance issues. Looking for a bit more displacement? Don't be fooled by sample pictures, we always show actual item pictures which means you will receive the exact shown. Whomever had this in the past ragged the poop out of it! It may have some strong competition in the V8 marketplace, but it often comes out on top, especially if you can find one at a bargain price!
