Is this all I need to know in order to ID my 5spd tranny and get the right parts for it when I decide to go through it and give it all the TLC it deserves:

"So:

0.745 x 360 = 268.2 degrees (1981-thru 1983) = 8:45 o'clock

0.773 x 360 = 278.3 degrees (1980 )_ = 9:15 o'clock

0.864 x 360 = 311 degrees (1977 thru 1979) = 10:30 o'clock

Just remember that the earlier the "time" the "Later" (meaning newer

model year) the box._ Before 9:00 o'clock is the 81-83 box, just

after 9:00 o'clock is the 1980 box and at 10:30 o'clock is the 77-79

box."

Thanks to Royce Miller and Carl Beck...

Just looking for a confirmation that there's nothing else to it...

Eric, I do not have any information for you but I do have a question. What does all the information you listed here mean??? Does it matter what time of day it is? JK

Serioursly though, what does all the info you posted mean?

What he is describing is how to identify the gear box by the ratio of the final drive. Put the transmission in fifth gear. Put a clutch plate on the input shaft. Mark the plate and note the mark's position, that position is known as 12 o clock. Rotate the output shaft 1 or 10 complete revolutions. Note the new position of the mark on the clutch plate and relate it to the original position like the hour hand of a clock.

Ok. Now it's been a year since I did this and I can't remember whether you turn the input shaft and read the output shaft or visa-versa
