Tried to remove the rear main seal retainer in my 312 engine but 3/8 socket is too narrow and 7/16 too wide. Tried 10 mm , it goes on the bolt heads but slips when I put some force on to unscrew the bolts. Which size socket is correct?

I just walked to garage..  mine takes 3/8 12-point    socket  regards Steve McD

Looking for McCullouch VS57 brackets and parts. Also looking for 28 Chrysler series 72 parts. And early Hemi parts.

Thank you guys! Checked the heads and they are not Allen type. The 6-point 3/8 socket seems too tight but I guess someone has used violence so I´ll make a new try with a 12-point.

Use a thin wall socket too. Chuck

Cruiser, The head of the bolts are 12 point... That's why a six point socket won't fit.

Worked out with a 12-point socket, thanks!
