They are a weird bolt. If you search a bit you should find a thread. Try calling mazdatrix to see if they carry them. They have a weird end that is tapered to make them easier to start. Not something you are gonna find at the hardware store.

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)

.
This is what I found on the archive, but Im really comfused, can anybody clear this out for me, which one of these are the ones from transmission crossmember to body. Im assuming the diameter is 14mm, but whats the lengh between threads, and bolt size from under head

To me anyways,it looks like that list is what the Bolts are to hook up the transmission to the Rear of the engine.I am assuming that the First bolt is the Long starter Bolt,as it has a Nut.
and ya, the Transmission Cross member bolts are Tapered at the End,to Ease starting the Bolt into the Hole on the Frame rails.(echo!)..
Have you tried any other bolt on the Hole itself,without trying to put the cross member on?.the Bolts are not that Long,If I remember.Only about and inch and a Half or so.
