T56 Magnum to Bellhousing bolt size?
 

Trying to round up the bolts that I'll need to connect the Quicktime bellhousing to the T56 Magnum transmission. Anybody know the correct size? Quantity needed?

Thanks!

I'm pretty sure you need 8 of them, as I looked at the face of my Magnum this past weekend. Unfortunately I don't know the exact size though. :(

OK from what I was able to find out the bolts are M10 1.5 X 40 flanged head cap screws. I ordered a box of 25 from McMaster-Car for couple bucks more than GM wants for a single bolt. Let's hope they work...

Yep, 10mm 1.5 pitch, 40mm long. Sounds like you already sourced them, but I used ARP 772-1005 ... It's a 5 pack of polished stainless 12-point bolts in this size/length; you need two sets as there is 8 or so bolts that hold the trans to the bellhousing. There is also a black oxide version if you don't want to pay $23 for each package of 5 fasters.

BTW, I sent your BBC frame stands out today - let me know how they work!
