NV4500 to bellhousing torque

[rcamacho]

Anyone happen to know what the torque rating is for the 7/16" bolts from the tranny to an AA aluminum bellhousing?

I don't have a torque value for ya, but my 4500-to-bell bolts were metric. Something like M12 or so. I used a GM bell. Maybe AA uses SAE?

I'll check with AA. I just eyeballed the bolts and assumed SAE vs. metric.

I'm fairly certain mine were SAE, and 7/16". I just cranked em "good and tight"

Bolts are 7/16"-14 1 3/4" long. PO had GR5 bolts so I upgraded to GR8.

I'm curious if the aluminum threads on the bell can take 55ft/lbs or should I keep it down to 35ft/lbs (wet with locktite)
