Heymowers, 

   For those of you using the Peerless 700 transmission and wanting to make a mounting plate, the attached picture shows the pattern. 

   And if you need gears and gear ratios (the numbers preceding the Gear Part Numbers are the number of teeth on the gears): 

7xx-Series (702, 761, etc.) Transmission Gears
Powdered Metal         Steel
Teeth    P/N            Teeth    P/N

25   778123A
22   778122A
20   778121A

25   778127A          15   778136

                              28   778202
                              31   778208

Gear Ratios: 

12:37 = 3.08:1 
15:35 = 2.33:1 
16:34 = 2.13:1 
18:32 = 1.78:1 
20:30 = 1.50:1 
23:27 = 1.17:1 
25:25 = 1:1 
28:22 = 0.79:1 Overdrive
31:19 = 0.61:1 Overdrive 

Input Gears

Input Ratio is 3.00:1 for all 700 transmissions (14T:42T). 
The 14T Steel Input Gear is P/N 778176 and the 42T Steel Driven Gear is P/N 778154.  Note that this Input Gear is the one that requires the 3-piece needle-style thrust bearing.
The 14T Powdered Metal Input Gear is P/N 778113A and the 42T Powdered Metal Driven Gear is P/N 778137A.  Note that this Input Gear is the one that only uses one thrust washer.

Rodney,
Thanks for the info. 

Do you have the part numbers for a steel pinion gear and ring gear for 700 trans?

Thank you,
Rob

Rob, 

   You're most welcome.  Sorry for the delay in Replying -- I haven't had much time lately to spend on the site. 

   To answer your question, the 14T Steel Input Gear is P/N 778176 ($26.00) and the 42T Driven Gear is P/N 778154 ($85.00).  Note that the Input Gear is the one that requires the needle-style thrust bearing with two thrust washers, one on either side of the bearing. 

Respectfully, 
Rodney
