G'day all. I need a mount/rack for the ARN-83 receiver -ADF- also commercially as Collins 51Y-4. Usual avenues explored.. avionic surplus et al-- score nil. Must have connector with it or separately --DPXB-45 -33S-0201 Have faxed Bill Perry but no response either way for this plug. The mil number for the same rack is MT-3605/ARN-83 Thanks Pete VK3IZ
