Maybe I should buy that rod!
Well that was extremely helpful - THANKS - in that I know what the dimensions are for a lever from a known floor shift Javelin of the 70s (72-74) but now I'm more baffled than ever before.......... That is saying the lever I have is dimensionally correct - the hole distance is correct, at least for 72 and there is zero reason to believe there should be a lick of difference between 72 and 73 (*I could look in my parts book to be sure but doubt I need to) So you have settled that - the lever length is correct at 3.125" center of link hole to center of selector shaft D-hole. Again, THANK YOU. That absolutely settles that question. I got a rod from the same person I bought the sifter from - but it was several inches too short. I lengthened it. In my thinking there should be no difference as long as the length is correct (and it has to be to get the shifter to lock in park with the transmission in park) but I am curious now and would FAR FAR prefer a CORRECT rod we know is correct in length AND angle - so perhaps I should find a rod to buy and KNOW it's correct. I hate guessing..... and if all else fails, the pan will be dropped from the transmission and the "cam" checked.... but that's a pain I'd rather avoid if I can.
Again, mega-thanks. That is EXACTLY what I was looking for and settles "what is correct" as far as the lever size. |

I dont know if there is a difference, any chance your shifter is from a 71?

Who knows?
Not sure how one can tell!! Maybe I'll have to dig through parts books. That's a great question, though.
Now you really make me wonder. Rats. |

A 71 is no different than a 72 on up, as for functional design. The 71 has a provision for mounting a rod and GM type NSS. The shifter arm to the shift rod is the same and so is the pivot point on the shifter itself. Edited by 304-dude - May/14/2018 at 7:21pm |

Functionally the same, yes, but dimension as far as the total throw from P to 1 the same? Is the distance from the pivot of the shifter to the center of the rod hole the same? In other words, from P to N and then from N to 1, does the 71 shifter move the rod the same as a 73 shifter moves the rod P to N and N to 1? They could look the same and fit the same and even the top part be identical - but how far that lower half moved not just in total, but between gears could make a difference. The only tell is to look in a parts book and see if the shifter part number is the same...... I found a rod for sale on eBay that says it's a one year only rod for a 71 - and it looks shorter than Scott's picture here.
So apparently there IS a difference in the rod........... I guess I dig out a parts book and compare part numbers of the shifter itself. For the shifter to be identical, it would mean that the B/W transmission shift lever would have to be identical in throw from P to N and N to 1 as the 727. That I question........... |

Here is what I found and it took some serious digging because my 71/72 parts book is a disaster - it wasn't well kept and the dividers aren't there and some pages are missing.
Anyway the shifter itself is the same and the base is the same. BUT - the rods differ and the LEVER is different between years and engines. The lever for 73//74 with 360 or 401 is 3219209 The lever for 1972 360/401 is different part number - 3213545 The lever for 304 is different and is part number 3213544 of course it's not a 727 behind the 304 So, the lever for 72 is different - at least part number, than for 73 and 74 The shifter itself is the same - the first book says part number 3211283 is for mod 70 1971/ which means 71 and later - and for that book that means 71 and 72 The later parts book says part number 3211283 is for 73/ which means 73 and later mod 70 So it all means the SHIFTER itself is the same 1971 through 1974 70 series. The rods differ and the LEVER is different. Again, the lever for 72 with 360 or 401 is 3213545 the lever for 73/74 with 360 or 401 is 3219209 Shifters are the same Rods are different for 71 but 72-74 use the same rod. Levers are different 72 than later 73 and 74
So the shifter itself won't matter. I bet the rod I have is for a 71 and that's why it wasn't long enough. |

-IF- I am correctly reading the 1967-72 Parts Manual, YES, the same LEVER was used for Column Shift and Floor Shift... But... That Parts Manual covers ONLY the 1st Year, 1972, TF Trans & Shifters. I lack having available on-hand the 1973 & Up to whatever year Parts Manual. Glad to see someone had, measured, photographed, posted a "known" Lever.

As long as the shift lever to the trans is proper length, and rod is proper for tranny the ratio does not need to change at the shifter.
IMO the lever will change accordingly to make proper ratio, not the shifter it's self. The shift rod is just a link between the shifter and shift lever, and to provide proper clearance. If there Is a different part number for the shifter, It's because of the provisions needed for a BW NSS switch to function. |
