I think everybody will be looking for a capable person that can create adapter plates that don't charge $900 for a $25 piece of metal. Even at just under $500, it would be a plus.

the reason many charge high rates for adapter plates is that locating the center point of the input shaft relative to the transmission bellhousing bolt pattern isn't a tape-measure-and-guesswork job - fractions of an inch out, and there can be nasty vibrations that will shake your car to pieces. A proper adapter plate should also have milled holes for locating dowels and threaded bolt holes where the OEM engine block was threaded, etc.

Once someone has invested that much time and energy into designing a precision tolerance part, then made the CAD file, cut a slab of aluminum on a waterjet table, then machined the holes and installed the OEM dowels, they want to be sure they make back enough in low volume sales to make it worth their while.

I agree that $900 is on the high side, but $25 is an extreme under-valuation.

I didn't imply that it was worth $25. Only the metal, and I would never think that someones time investment is worth nothing. I just think that
$900 plus is too pricey for the segment they are selling to.

In that case, I apologise for misunderstanding you.
