Need custom clutch disk, need vendor advice.

Honda L15B7 motor, RWD BMW 323i Getrag transmission.
A custom adaptor plate/ring to mate the two.
Both have dual mass flywheel, and clutch disk is nearly equal size and configuration.
I have a solution for the input shaft spigot bearing.
But the offset distance of input shaft splines to clutch will likely require a custom disk hub.

Any advice or referrals on vendors or providers?

Thanks,

Spec clutch did a couple custom ones for me in the past. Don't know if they still do, but i am really happy with their stuff

I've read that Clutch Masters can get you setup after you provide some needed dimensions.

www.phoenixfriction.com has done  a great job of finding weird clutch combinations based on clutch specs for me in the past.  I don't know if they do custom or not but if there's a way to do it with off the shelf parts I have a high level of confidence that they can figure it out.

Thanks for the referrals folks.

The Getrag input shaft is 1-3/16(1.188) x 10 spline.
I estimate that the required offset will be between 1 to 1.5 inches (25-37 mm)

The DMF unsprung clutch disks are commonly made with a plate to carry the friction materials, having either the
center female splined hub welded on, or a flanged female spline hub riveted on.

If an existing female splined hub with sufficient offset exists, it could be a simple solution to assemble from off-the-shelf donor parts.

If not, then the splined hub could be fabricated, but the cost and difficulty are unknown.

Guess my next move is to capture the required dimensions, and reach out the vendors to get estimates.

These guys once did an adaptor and clutch set up for us for a 12A powered BMW 700.
