Both belts should be the same cross-section and it sounds like the Variator Pulley>Gearbox Pulley belt is still original, so at least you’ve got some dimensions.

By the way- your part number is incorrect; it should read MBA4471 for the engine drive and MBA4472 for the gearbox drive belt. The parts listing doesn’t give dimensions, just the description which reads, “Vee Belt- Engine Drive”.

Best of luck.
