I would suggest a 1972 or older chev, gmc(the same truck) in a c10 not a c20 and 2 wd. the c10 is a half ton , c20 3/4 ton. You can get with a 350 cid v8 2 barrel carb.,much better ride , better on gas. when you rebuild the engine drop the compression down to 9 to 1 or less. And best of all. all the aftermarket parts are online at very decent prices, the drivetrain, sheetmetal, interior,paint, very easy to restore . The rover you mentioned is a nightmare, the english should not be allowed to manufacture vehicles, no disrespect intended to those present from the uk!!!! when you are finished the chev-gmc truck will always be worth much mony, the rover will not, no fun to drive , worse to fix .
