1973-1984 cab floor clutch rod hole size

[BIGJAKE97]

I put a 1978 4x4 automatic cab on a 1978 4x4 frame with a sm465. I found the 3 dimples in the floor where the 1973-1984 clutch rod goes through the cab floor. I know the clutch rod goes through the middle dimple and the two outer dimples are for the little bolts that hold the clutch rod boot, but can someone please tell me what size the center hole that the clutch rod goes through is suppose to be? Thank you

Heres a old thread that has some info in it.
If no one gets you a answer I'll measure mine in a day or so

Do you have the boot that goes on the clutch rod?

[BIGJAKE97]

No, I do not. And I know they are hard to find.

Bigjake, just went to measure my 76 cab for you, but it is too rotted around the hole to get a measurement. Sorry

[BIGJAKE97]

Thanks for the time spent trying to measure it for me

Yesterday we put the SM465 and NP203 back in my 74 K20….what a pain in the arse doing it on the floor.

I’ll see if I can get a picture for ya

I measured on cab I had, it was 1 3/4 hole, but not sure it was a factory hole. the boot looks like it will easily cover a 2" hole.
