Hello Everyone, I am llooking for the right angle speedometer adapter that is at the Muncie M20 side of the speedometer cable. I’m not having luck locating this part or a replacement. Anyone have one, know where to get one, or suggested alternate part?
I have those ...
but...
they are also used as a speedometer corrector .... when doing a rear gear or tire diameter change ..
like .982 .878 ratios ....just examples ... not actual numbers
I dont think any are 1-1 tho ...
I can took tonite
It would help to know what year your car is, what gear you have in the rear end and if you have changed from the factory tire size. I have a few of these adapters. Thanks, Bob.
Just curious. I've seen a right angle adapter when using a passenger side speedometer Muncie in a BOP A-body drivers sided speedometer cabled car. I always thought the right angled one was only so one could use the existing cable. I had a 1965 Malibu SS (first year of passenger side Muncie speedometer) and it was passenger side speedometer Muncie. I believe BOP were drivers side to 1970 then all Muncies went passenger side. Do you need the "correcter" or the cable "enabler".
Thanks for the replys. What an awesome group! I guess I would be looking for something would come stock with the M20 1968 442 Muncie with 3.42 gears. I’m not sure what size tires that I am going to end up with. I thought that you could put in the different speedo gears for what setup you have. I’m clueless I guess I just thought there would be one kind of adapter to make it 90 degree angle.
If your car came with a 3.42 rear and still has the wide ratio M-20 than the correct ratio adaptor is 1.1320.
They were made by Stewart -Warner.
Mine was broken when I got my '69 and I needed the same one. I hate to tell you It took me 20 years to find one.

Reason: spelling
I was using a right angle adaptor that i bought years ago for the tach on my Corvette. The tachs are gear driven off the distributor, as it turned out i was better of without it on the Vette. So adding a Gear Vendors OD to my car seemed to put the speedo cable in a bit of a bind and i used the tach drive adaptor. It worked great until it came apart. Any Corvette vendor would have it, Ecklers, Mid America, Zip. I ended up pulling my cable up some and it fit after all on the OD, so i never bought another adapter. Not sure why it came apart, it looked pretty stout, but it did. They do not change the ratio its just one to one.
Hope this helps
So the adapter 35tac is talking about on EBAY in the post prior to mine, is the same as i used, If you get one perhaps you should lock tite the threaded parts so it dosent come apart.

This is what I was talking about so a driver's side cable would reach a "passenger" sided transmission. I believe BOP had driver's side Muncie transmissions till 1970 then they went to the Chevrolet styled passenger side which Chevrolet started in 1965, jmo.

Hey im actually lookin for 1 of those as well I have a 66 muncie 4spd. speedo connect is on the drivers side of tail section. i have a dakota digital gauge set so it can be programmed to accomodate the gear ratio.
Would you be able to provide 1 ? ....Manny cruzcorp1@gmail.com
It looks like you resurrected an 8 year old thread , but I have several….i thought I had more…..these came from my dad’s repair ship so I don’t know the history. These are 3 Stewart Warner adapters with ratios ranging from .8241 to 1.3900….i always thought this was the Chevy type but I don’t know. Anyways I have these. Maybe someone can chime in and help. The one with the masking tape is marked Chevelle 4.10 but don’t know. It says 1.2020
