Tranny mount (Bolts)

So I looked in the archive and found this

Engine / Tranny Mounts:
(1) 14 mm head - Length = 145mm (5 5/8 in) (with head of bolt)135 mm (5 1/4 in) (from bottom of head of bolt to end of bolt). Nut on opposite end. FINE THREAD
(1) 14 mm head - Length = 100 mm (3 15/16 in) (with head of bolt) 90 mm (3 1/2 in) (from bottom of head of bolt to end of bolt). FINE THREAD
(2) 14 mm head - Length = 45 mm (1 3/4 in) (with head of bolt) 35 mm (1 3/8 in) (from bottom of head of bolt to end of bolt). FINE THREAD
(1) 14 mm head - Length = 40 mm (1 1/2 in) (with head of bolt) 30 mm (1 3/16 in) (from bottom of head of bolt to end of bolt). COURSE THREAD (goes under the starter)

But what is for the tranny mount to the body? I am getting ready to put in a turbo conversion, but I am not sure what bolts I need to get to bolt the crossmember up.

Are you missing the original bolts from the NA mount? They're going to be the same thing as you'd use for the turbo mount.

Yes, I am missing the original bolts. Through the search I have found Japan2LA has them available and they are some special bolt. One thing I did find was someone stating they were able to use the same bolts as the seat bolts. These would be easy to source if that is the case. Can anyone verify this?

In case anyone else is interested...

I just got back from the wrecking yard. The seat bolts are an exact fit for the crossmember bolts. The only question is if they are the same length, but they fit none-the-less.
