Need to know which engine-bellhousing bolts to get I am converting from auto to manual and the only things I have left to get are the engine-bellhousing and the bellhousing to tranny bolts. The dealer said the engine-bell bolts are 12x1.75x45 (need 11) and the bell-trans bolts are 10x1.5x40 (need 6). Can anyone verify this? And the dealer wants about $5 per bolt, so I will be getting them elsewhere. If I go through Mcmaster should I get 316 stainless or grade 10.9 zinc plated or black steel? Will I need any washers? Thanks I just want to be sure I have everything before I get started tearing things up.

Lucky you, I'm in the middle of doing the same thing!
engine to bellhousing: M10x1.5x40 You need 8 of these + washers
bellhousing to trans: M10x1.5x40 You need 8 of these + washers
I got 10.9 hardened black steel from the local hardware store. The only thing you'll run into is the size of the heads. The factory bolts have a smaller 13mm head, while the hardware store bolts will have a 17mm head. This could make access to some of the bolts difficult. I didn't have any problems because I only needed to replace a few bolts, not all of them. Hope that helps.
