Re: Build that 71 402 already
Pulling the engine Saturday with some assistance, but today I pulled the transmission. So easy with the transmission jack.
Interesting set of bolts for the transmission to block. Can't swear they're factory, because we pulled the engine once. From my observation, we were real good about using the same bolts, and none were added.
Two (Grade 8) 9/16 flange bolts. Bolt threads are 3/8-16 x 1.3/16, of which 5/16" is shaft. Heads are stamped with a circle.
One (Grade 5) 9/16 flange bolt. Bolt threads are 3/8-16 x 1.3/16, of which 5/16" is shaft. Head is stamped "A".
Two 9/16 flange bolts. Bolt threads are 3/8-16 x 1.3/16, of which 5/16" is shaft. These are unusual, because though they're flange bolts, the heads are not recessed. That and they have four markings, so I can't say what grade. The heads are stamped "IiL P SiB".
One (Grade 5) 9/16 flange bolt. Bolt threads are 3/8-16 x 1.1/4", and no shaft. Head is stamped "M". This bolt was used to retain the transmission dipstick tube and vacuum retainers.
