The factory rear strap anchors in the trunk floor get covered by the larger GP tank (the tank dimples fit right over the anchors). When I pulled the GP tank, I also took the longer GP straps.

Once the tank was in the A-body, I had to make mounting provisions for the longer straps by cutting into the cross brace tunnel at the back of the trunk, behind the bumper. The straps kind of land in a 'natural spot,' so it was easy to figure out how to notch and re-anchor the longer straps.

Been holding up solidly for thousands of miles now. Nice to have the extra capacity.
