OK, now I understand the no LL deal.
The rear in your car was used on a lot of different bodies, including station wagons and some light trucks. Don't know how the rules view it but you might want to look at the possibility of using wider brake shoes if you can. Might require changing backing plates, you just have to look at what size shoes are available. I know on 9" Fords there is a lot of different rear brake configurations.
