Had some bolts that loosened up and fell out of my new truck. Can anyone who has an NP241C (it's in a 1992 Chevy K1500) out give me the size of the bolts that hold the front driveshaft on the transfercase and the four bolts that hold the adapter to the back of the tranny (700R4). All four fell out of the front driveshaft somewhere along the line and three of the others backed out and one is gone.
Thanks.
Call Autozone, they might be able to look it up and give you an idea of what size to start with.
had that happen to me... but i never did actually look for the size, just took the remaining one i had to compare to... i think it might be a 3/8s course thread tho...
They are Metric on mine. The transfer case/tranny bolts are 15mm headed. I guess I could take one out but then I'd have to drive the truck to the hardware with only two left. lol, can't win for losing with that. Driveshaft bolts are all gone so I don't even have one to take up. Worst part is I junked a truck last year that woulda had all the bolts I needed! loll
on older the head is 5/8 and coarse tread.. but if u re saying yrs is a metric then i cant help ya cuz i dont know
just go to a junk yard..
I wanna. Say they're M10x1.5. 3/8-16 will start to thread in but will stop very soon. Driveshaft might be M12x1.75. They're usually a fine thread. Larger bolt... grab a handfull of bolts from the hardware store.
just do what ohearn said and go to junk yard and find the same truck and take out of that eliminats the guessing prob. thats what i had to do with my 83 s-10 3 or 4 of the bell housing bolts fell out at some point. didnt feel like guessing on new ones

You were right on about that one. The driveshaft did end up being standard 7/16x???. Or at least close enough for them to work.
Thanks for the help everybody.
