1939 Plymouth TJR Right Hand Drive Throttle Link

[eh dubya]

Hi all, searching for pics, p15-d24.com is clearly the best source but nowhere could I find a pic of any '39 pedal end of a throttle link. I'm puzzled just how it was done, I was kindly shown a picture of a '38 which uses a short straight pedal rod attaching to a bellcrank and firewall mounted cross shaft, with this setup the bell crank pokes back into the rectangular hole in the body mount.

As far as I can establish from a multi year part list 39-41 LHD US cars were peculiar to themselves but 39 Plymouth book lists no less than six RHD  pedal rod part #s. I'm told the local Canadian sourced cars simply have a pedal rod to a manifold mounted bell crank.

I attempted to use a straight pedal rod and the redundant clutch pivot but that geometry causes the shaft to move fore and aft in the floor hole too much. The '39 has a round hole above the rectangular one right side only and it appears to have been filed for clearance suggesting it came through there, strange as there's no sign of a bell crank mount.

Any clues would be much appreciated as I not even been able to find a picture of a LHD one.

EH...........can you be clearer as to exactly what your car is?..........is it LHD or RHD and where are you?............as for Oz built RHD cars they used a rod that came up from the lower firewall thru a hole in the removable floor and attached to a bellcrank which was almost identical to the bellcrank the LHD cars used in their linkage which in the LHD cars went beside the engine block then hence across the cylinder head......the RHD setup was MUCH simpler than the LHD.................so what car do you actually have?..............andyd

Andy it's a 1939 TJR Plymouth RHD as per title. The top picture is it, the second pic is 1938 TJR.

My 1940 Oz car used a rod that came thru the floorboard that was a press fit into the top rear of the accelerator pedal into a rubber hole, the pedal pivoted on 2 round balls at its bottom which allowed the pedal to move back & forwards pushing the rod thru the hole and operating the carby bellcrank that was on the linkage.........the bellcrank was located via a pivot shaft that bolted onto the side of the intake manifold...........I'm going on my memory now........that of the 1940 Dodge that I replaced all these bits on in 1973 and the 1941 Factory RHD Plymouth Coupe which I owned from 2007 to 2014......................I'll see if I can find a pic that might help.........does your car have the stock accelerator pedal and carby but no linkage between the two?................andyd

Pic below is from 1938 Detroit assembled D9 Dodge. Largely what others here refer to as a Plymouth based mopar but with Dodge trim. It is a bit more nuanced than that though. This vehicle was made for the New Zealand market and is RHD. Linkages are shown in engine bay. How it connects to the accelerator pedal at the driver's feet is exactly as Andy describes it.

Your 39 will be different to this as when I look at my 1938 Parts Book that covers all Chrysler Corp vehicles for 1938 ( left and right hand drive, Export and Domestic ), none of the parts no.s that are in your picture are found. The engineering changed between these years.

Thanks Andy and Pete, I have a stock pedal centred in the floorboard hole when flat and 1997 Wrangler 4.0 cable to pull. It's the geometry of the of the pedal rod that's the problem.

Petes '38 pic is very interesting, cleanly using the upper hole (unlike the TJR '38 I posted), I imagine there's a pivot connecting the pedal rod hidden behind the hole. it confirms a '38 setup would work but I'm reluctant to go that way yet without knowing what a '39 looked like. 

That's such a nice pic Pete, thank you very much for it and confirming the numbers/difference.

The elbow piece of the rod that disappears into the hole in the firewall is one piece. It has another bend in it that lines it up to go through the pedal rod grommet ( rubber with a steel centre hole ) that is located in the floorpan of the car. If you enlarge the pic below you can see it in the gloom with the rounded end that the gas pedal is pushed onto. Below that are the two round studs permanently fixed to the floorpan that the gas pedal is pushed onto and pivots on.

Great stuff Pete, it's interesting that Terry's TJR '38 I posted has a short straight pedal rod and pivot in there between the floor and exit holes. Good to know it's not necessary.

Those look like the Steele pedal pads I have, I was a bit disappointed with the colour being nothing like my brown accelerator pedal or shifter boot.
