If it helps, I have the 65 page (pdf file) of the January 1956 Installation Instructions for Radio Sets GRC-9 or SCR-694 in Combination With Radio Sets GRC-3 to -8, VRC-1 to -3, VRC-8 to -10, VRC-16 to -18, PRC-8 to-10, and SCR-619 for the M38 and M38A1.

It has the drawing that Wes provided above, as well as dozens of others for cables, brackets, and mounts, including antennas.

I'd be glad to email, or perhaps it could be posted in the radio manuals section of the downloads page?

Hi Pierre,
I'm not allowed to upload stuff on the website.
I'd be glad to email it to Wes so he can upload it to the radio manuals section of downloads.

Hi Lyle,
I just now discovered that the email server I use has an attached file size limit so I can't send it via email.

I did go back and research where I originally found it --- and here's the link so you can see and download it for yourself:

Hope this helps.
Sorry for the confusion.
Good luck!
