Mini Starters on a Slant Six

Update to this post. Do not buy the Mini-starter from this place! It is junk and I won’t use it.
It would not disengage from the flywheel. They said shim it. We shimmed it and it still didnt work (awful sound!) they said shim it up to 8mm! Umm no thanks. To me if you have to shim something that much, there was zero care into putting this together. And their 100% satisfaction guarantee is nonexistent! They will not let me return it. ****’s

I’m still very thankful to Slantsixdan on all the knowledge he shared here!
And it looks like he is still correct in saying nobody makes a mini-starter to replace the direct drive starter. So my search continues.
I might be a little less angry at the supplier for that rare starter, especially since it seems there is no alternate product. Put yourself in their shoes, considering it is a very small market, selling maybe 6 starters per year if lucky, and perhaps your car varies in some way. I say that because for my older M-B there are choices like $170 for a set of door weatherstripping from aftermarket company URO vs $650 for a M-B brand set (if can find). Purists rant about "never buy from URO, because ...". But many of their parts are fine and affordable. They even visit owner's forums and listen to owners and adjust their suppliers. For rarer cars, it can take teamwork to keep them on the road.
