Yes Rover Sherpa Is Good And It Has The Larger Stronger Bearings, Its The Same Build Box As The Vittess Box , I Have Just Rebuilt My Lt77, I Have Built Lots Of Gearboxes From These Lt77 Up To Volvo Fh 16 Truck Boxes And They Are Ok If You Take Your Time, But The Lt77 Is Only Realy Good For About 250 Bhp, I Run Tqf In My Lt77,you Can Run Synthetic Oil, But It Foams Up Slightly More And Creats A Number Of Air Pockets, Where As The Tqf Will Not Do This As Much, Plus It Has A Lower Viscocity When Starting The Engine, Which Helps The Oil Pump Run With Less Resistance, But This Is Only My Opion, Hope This Helps
