1969_Mach1 333 Report post Posted October 8, 2014 Hello, I have a restored 1969 Mach 1 and after many years I am finally installing a radio. For me it is more to fill the opening in the dash and having a period correct appearance. So, I purchased a period correct New-In-Box NOS AM/FM 8-track. It is not an original Ford item but an RCA replacement from back in the early 1970's. It fits perfectly and even has correct wiring adapters to connect to the original wiring harness. Question: Where do I find knobs for this RCA radio? The original Ford knobs fit D-shape shafts and this RCA radio has round shafts with slots in the middle. I guess you can call them split round shafts. The shafts are the same diameters as the original radio's, just different shape.

danno 128 Report post Posted October 8, 2014 Is it just one knob per shaft, or two? The original radios had 2 knobs on each shaft, one in front and a larger one in back. Does this have double knob shafts? If it does not, and you do not care about period correct, I might have a couple I can give you. Quote Share this post Link to post Share on other sites
1969_Mach1 333 Report post Posted October 8, 2014 Thanks for the offer. This RCA radio has two knobs per shaft, a smaller in front and larger one in back. I saw on EBay the two larger rear knobs for a later Ford, 1974 that looked somewhat period correct and like they will fit correctly. They are NOS being sold by Perogie Enterprises. I'll have to phone Perogie's to find out if they have the front two knobs as well. Quote Share this post Link to post Share on other sites
1969_Mach1 333 Report post Posted October 10, 2014 To follow up. I was thinking of filing a flat spot on the shafts to make them D-shaped for each Ford knob. And after close inspection I discovered the shafts on this RCA radio have flat spots (D-shaped) as well as being slotted. So the original 1969 Ford reproduction knobs fit correctly.

danno 128 Report post Posted October 10, 2014 OK, then you should be "good to go". This assumes you have the correct knobs. Again, I have some if you need them. Quote Share this post Link to post Share on other sites
