Do you have a picture of specifically what you need measured? Or a more detailed description of what you're after? I'm a little confused as to which piece you need measured.
One is telling me the rubber boot in the floor that needs cut so the Hurst pivot sticks through it. The other is telling me the shifter boot(what you see in the car) that the actual shift arm sticks through.
Re-read and now I understand.
The Hurst shift arm where the boot "rests" is approx 1/4" thick and 7/8" wide. Precise measurement is difficult as the stock is more of an oval on the 1/4" thickness edge. Plus I can't find my calipers. haha.
The Hurst boot hole for the shifter is approx 3/8" by 7/8". This measurement is off a not beat-to-hell boot, but also not a brand new one either...no cuts.
Some things to keep in mind.....Hurst arm mounting holes are 7/8" on-center and 3/8" holes. Ball thread is 3/8-16.
So you're making your own Hurst-like shift arm?? Cool! What're your ideas?
And for reference....measurements off my truck that's currently half taken apart around the shifter. Stock Hurst Ranger arm and the boot it comes with...
