I am presuming that it is a normal v-belt and not a serpentine belt

Belt needs to 9.5 mm or 10 mm across top x 875 mm long

There is a lot of vehicles that use this size 9.5 [10] mm x 875 mm, very common size

Possible part #'s:

9.5mm size:
9.5X875La,

10mm size:
10A0875, 10A0875C, 6215ESC, 6215MC,

The 10 mm will sit up a little higher in the pulley but should be ok

If all else fails this might work ok:
GATES Part # 7345 {High Capacity V-Belt (Standard) HC41 3/8" x 35 1/8"}
this might be a tad long ? as 35 1/8" = 892 mm
