I've been working on a 1988 Raider. The starter gave up. I thought I'd replace it with a standard Monty 2.6 liter starter.

Here are web images of a typical Monty starter --






But this starter is different!

The starter is much larger than the OEM components.
It appears to have a gear drive that the standard starter lacks.
While the standard Monty starter has a partial cover over the starter driveshaft, this one fits directly into the engine and lacks the hemispherical cover.







This IS the starter from this engine. The engine originally came from a donor car, a 1987 Montero. I had the donor engine rebuilt at a local machine shop.

Has anyone ever seen this starter?

What's it doing on this engine?

If someone knows this starter, that would help me find a replacement.

Any help appreciated!
