Which LT-1? Some had the alternator mounted up high, mine is down low. Do they all use the same belt?

The low mount. The higher mount was on the early models.

I have found an equivalent to the standard 72-5010 belt as no-one stocks them in Australia and USA online stores won't ship here. It's a Gates Micro-V belt with part number 6PK990 (6 rib, 990mm in length).

My boat is a 1997 Prostar 205 with the low alternator mount on the LT1 engine.
