I’m about to start building a Defender 100 inch hybrid using RR chassis with a 3.5 v8 on carbs with an LT95 4 speed box. I’m basing it on the 110 hi cap used in the first tomb raider movie “The Cradle of Life" but with a couple of changes. I already have a bulkhead with dash , 90 tub and seat box , wings and front end etc.... But after measuring a mates 130 I think a 130 hi cap tub should fit nicely without any modification, as i plan to cut the 90 tub down to make an extended cab or "king cab" , will this work ?
