So ive been getting ready to do a clutch replacement on my 92 4.3 2wd blazer and noticed the bellhousing is missing a couple bolts. One on top an one on bottom. The bottom look like something attached to it. Maybe a brace? Also does anyone know what size bolts to use for the bellhousing?

 

Not sure - could be a short bar which connects to the block. If I properly remember the 4x4 automatic transmission has something there.

Thread could be metric.
