GS 1100 Mitsuba Starter rebuild/replacement

[1Bigbear]

The starter in my '82 GS1100GL died due to oil seal failure. The Suzuki dealer says rebuild parts are available, but not the required shaft seal. Suzuki replacement is over $500 and requires additional $30 cover plate. "Ricks Motorsport Electrics" has a replacement for $185, but description does not specify my model and says "Mitsuba starters may require cover plate or return for rebuild"; so, I'm concerned I may get the wrong part wasting time and return shipping (if returnable). Can anyone offer assistance? The dealer says the seal dimensions are 25mm OD x 15mm ID x 6mm thick with steel OD ring and two ribs or ridges on the ID. The dealer rebuild, (if possible), will be a comparable cost to the aforementioned replacement so if I could verify this replacement would work I'll go that route and replace the cover if necessary.

82 GS1100 info

Thanks for the link. They even have complete rebuild kits. I also found a site for oil seals that may help those in need; Harwal oil seals @ harwal.com .
Lots of info on materials and different configurations. I'll probably use Stockers for a rebuild kit or one already rebuilt to minimize brain strain. Thanks again
