    The actual bolt size and thread or the socket size?

    I believe they are 7/16" coarse thread bolts that are roughly 1.5" long grade 8. I believe the socket size is 9/16" or 5/8".

    Well to throw a monkey wrech into bolt sizes, one of my a-bodies ( 76 ) and my g-body ( 78 ) used a 19/32's wrench to turn the bellhousing bolts , I think thas equivalent to a 15 mm . Chit you not , none of my other bellhousings used that :grin:

    Those are 3/8"x 16 TPI...and should be the shouldered head variety, approx 1.25" long.

    Speaking of those, I have one busted off on my truck...:doah:

    What he said. And if you need the bolts for the front output of the 208 they are 1" long 7/16" coarse thread bolts. Grade 8. :D

    P.S. a 9/16" gear wrench is a life saver when you are working on those adapter bolts to the Tcase. a 5/8" gear wrench is great for the output bolts.

    My front output bolts are fine thread...I'm almost positive (almost, but don't feel like pulling one out to see.:) )

    Mine are definitly coarse thread. I have one sitting on top of the TV in my room. I lost 1 once when I was rebuilding the 208 and I got 4 new bolts and the old one I used to match it with is in my room.

    Ok, my truck is on another continent so you know I'm not cheating. My 465/205 combo uses 3/8 coarse bolts about 1 1/4" long. They use take a 9/16 wrench and standard torque for that size bolt is 25 ft/lbs.
