What size trans to engine bolts?

[89stang10sec]

Please help, I am assembling a 5.0 drivetrain in my 89 gt and do not have any of the bolts that attach the trans bellhousing to the block. T-5. I know it takes six bolts but I need to know what size bolts, and length to buy. Thanks

I used 7/16" 14 coarse x 3" on my stand. I would think you could get this in a grade 8 at any bolt place. I think the stockers are only 2" instead of 3" needed to clear my engine stand.
