I have a 66 442 -vert I have deciphered must of the codes but still some of codes are a mystery or I get conflicting info. I have no build sheet so some items are are open for debate. I'll go through what the car has
Power windows, Power driver seat, A/C 4 speed with a console, Tilt wheel, Although some of the power options I beleive came from a 67 A body, because the steering wheel that came on the car has the 3 spokes, and the tilt wheel has emergency flashers, correct if I am wrong but the flashers did not appear till 67. The rear end code listed it as 3.08 to 1 ratio, has probably been changed,?? the transmission shows a date code for a 66 and is a M-21, What got me thinking was there was no verification on the 4 speed my body man says it was original although the floor hump has had some surgery, maybe just repaired at one time,but the rest of the pans trunk etc look original. I know alot of the options won't show on the cowl tag but I would like to know just what the codes refer to. So here goes, my questions are the capitol W after the date code, I am assuming it was made on wednesday 2 week of October ??? Second question line 4, EX 2KLG, some say this has to do with the 4 speed seems I de-coded the EX portion as A/C ?? You guys that know these cars better than I can possibly shed some light
Thanks

10B W
ST 66-33867 LAN 481 Body
TR 980-B J-2 Paint
EX 2KLG
5VY

 

TR 980-B J-2 Paint 980 = black B = bucket seat J = forest mist 2 = black top
EX 2KLG E = power window 2K = Air conditioning L = 4 speed G = console
5Y = deluxe seat belts

Thanks, the 4 speed and console was my main concern also nice to to know it came with power windows any luck with the capitol W on the top line. I have put it back to almost it's original glory with the forrest mist paint black convt top etc etc. The 3.08 rearend had me puzzled, the M-21 did not come with the 3.08, I will check the #'s on the transmission again and try to verify which part - trans or diff was changed
Thanks again Dave

 

Henry, I'm pretty sure you know this, but just slipped up. The E is for tinted glass and the X is the power windows

Dave, are you sure the trans is an M21 and not an M20? The 3.08s were optional with the M20.

 

Take a look at the build date on your trans, with a 10B car you should have a Sept built muncie M21. 442's standard ratio gears were 3:55's with with 3:90 as an option.

According to the Product Information Manual, the letter in that location has an association with the build month, but it doesn't seem to relate to it from what I've seen. Doesn't seem to be a anything significant.
