Are they the original four cylinder t5's or are they v-8 t-5s? Also, if not original do youo know what year or brand they are?

On the passenger side of the transmission where the tail housing is bolted on to the main case, there is a metal trim tag on 1 of the bolts. On that tag are 2 rows of information. If you can find the tag and post the letters and numbers off of it, I can decipher it for you.

Most of the T5's came with a 3.35 1st gear, 1.99 2nd, 1.33 3rd, 1:1 4th and a .68 5th. Some came with 3.75 1st gear, 2.19 2nd, 1.44 3rd and 1:1 4th with a .72 5th.
Still yet, others came with a 2.95 1st, 1.94 2nd, 1.34 3rd, 1:1 4th and a .63 5th.

Because there are several options, we really need to know the numbers on the tag.
