Screw and bolt sizes
 
can anyone tell me where i can get size/info on bolts.. specifically for the tranny area?

I'm not sure if such info exists. If you don't have an example to go by, there are some pretty common thread sizes and pitches on the car that most of the bolts fall under ... I think these are right but don't take it to Vegas because my memory is silly: (dowel X thread pitch) ... 6mm X 1.00 (10mm head), 8mm X 1.25 (12mm head), 10mm X 1.25 (14mm head).

Take a look at this and it might help you:

http://www.metric.fsworld.co.uk/sispanner.htm

The first category is the stud/shaft/dowel size, spanner size category is the head size that you'd fit a wrench to with the first category being what you'd find commonly produced head sizes in the USA for metric bolts.

You can match threads using a tap/dye set and then measure depths (lengths) that you'd need (stick a nail in the hole if you have to), but that might be expensive if you don't already have a set of taps.

If you have an example, then any decent parts store will have a monkey who can figure out the thread pitch and dowel size with a tool.

I hope that helps.

The problem is I dont have the bolts, and dont feel like payin 2 bucks at the dealer per bolt, when i can get the same grade bolt from a local hardware store for 10 cents

Gotcha ... well plain and simply like I said there are 3 common sizes on the car (obviously with some varying lengths). Measure the hole width if you have to and it'll fit into one of the 3 sizes/thread pitches. Then stick a long nail in the hole and find out how deep it is to find out the length you need. I gave you the information that you need in my above post.
