This is the only place where I could actually find what I needed to repair an old Grohe shower/bath wall mount diverter valve/tap. The pattern for the actual ports was wrong but I only needed the nylon part that turns the valve. So I made it fit mine by using my old diverter port pattern on the new body. Not ideal but atleast we can now use the shower and bath as before. So it did the job and I can always make the new pattern fit with a bit of filing the locating pins if necessary.
