Our records on this one are thin — it shows up as a gearbox internal for the smaller singles rather than the big twins, but we don't have the full run of catalog appearances to point to specific years or models. If you're rebuilding a box and need to match this against what's currently in there, bring the old gear in or give us a call and we'll work through it with you before you order.
