We have a 1976 88" Series III, and want to make it safer, especially for back seat occupants.

Does anyone have experience with either of the following?

1. Installing a chassis mounted internal roll cage in an 88" (or if that is impossible, internal in the rear, external for the front seat)?

2. Installing a forward facing two or three person bench seat in an 88"? I've heard it's been done with Exmoor Trim, Jeep, racing seats, etc., but am hoping to talk to someone who has done it.

Thanks!
