Bell housing / transfer case bolts

[K5Rob]

Hey guys just got the LS dropped in my 87 K5 along with the 4L60E and the original to the truck np208.

Need the following bolt sizes has somehow I misplaced them.

- 2 bottom bellhousing bolts near oil pan (see pic)

- transmission mount stud nuts (mount to crossmember) there are 2 of them

- transfer case side bolts. See pic. These I have but forget if theres a stiffener bar or something that goes here? And is it necessary?

On a side note, I recommend relocating those knock sensors. Was tends to get into those areas and rust out the connections. Its a pain to have to pull the intake down the road to replace them. Or if you plan to leave them there, its best to dry that area very well and then use sealant on those black covers to keep water out. Then if they fail, you can just leave them there and splice into the wiring harness and add the new sensors to the front of the heads. Same threads, they screw right in.
