Default DRM 84 - 87 J55 brake Adapters?

I bought a used set of DRM J55 brake adapters of a member way back and now have parts to fit.
Anyone have pics or install instructions?
DRM no longer make these so no info online from them.

They appear to mount only one way and everything lines up correctly except I can not move the caliper foward to engage the original caliper mounts on the spindle .
The machined internal cutout of the adapter is smaller than the original mounts
Any experience?

Rodj,

Good Luck on your search.
Cheers,

Are you using these?

They still show up on DRMs web page http://www.dougrippie.com/drm/brake_...nting hardware
I have a different looking one.
The one I have bolts to the inside and then has spacers that go outboard to the caliper bracket.

Here is a link that may also help.
In it CC says "And it looks like those drm adapters fit just like i said.... those long bolts go in backwards, and the adapter mounts on the inner surface of the knuckle, then extends around it to be flush with the outer knuckle surface."

Thanks ,them the ones ,only the milled cutout is not large enough to fit over the two bolt eyes on the knuckle
Email time I think.
