Default What size bolts for bellhousing/tail shaft?

Hey, Im in the middle of an LS1/4L60E swap into my third gen, and I have a trans, but its in pieces. I wanted to know what type of bolts I need for the bellhousing into the trans, the tailshaft into the trans, and what size bolts for the bellhousing to the engine are.

Thank you guys very much!

Bellhousing to engine: M10x1.5x40, 13mm hex.
Tailhousing to transmission case: M10x1.5x27, 15mm hex.
Bellhousing to trans case: M10x1.5x45, T50IP (torx plus)

Bellhousing to transmission bolts are probably GM only. I've sold a set on ebay not long ago, there are some sets on there now for around $15.

Thank you Jay. I called GM on the tail housing, and picked up a few 10.9 bolts today. That should do the trick.
Ive seen the tranny to housing bolts on ebay, but they are 40 bucks or so.

Damn, I sold a set for $15 http://cgi.ebay.com/ebaymotors/ws/eB...m=220603387848
Could have sworn I seen others for around that price.
