    Toploader ID

    I have a toploader 4-speed with a very badly rusted code tag. The case number is C8AR-7006-D W-2 and the tailshaft no. is D0ZR-70A40A W-1. It has the small 1 1/16 inch input. The serial number found on the foward top lip is 8K108058. Can anyone tell me which tranny I have?   Thanks, Bill

    Not getting any closer to a definitive answer. Does anyone have access to a Ford Master Parts Manual?

    I found the case and the tailhousing basic numbers at David Kee as suggested above.  With some basic measurements on case tailhousing length, etc, you should be able to zoom in on it.  I suggest that you will have better success contacting David Kee directly.  You can also put it in gear and determine close or wide ratio.  Look at the section on ID CHARTS and it has separate listings for tag number, case number, and tail housing number.  Looks like a standard case from 68 to 71 a tail housing from early 70's and based on that you can get awfully close.  The numbers listed also show key dimensions, spline counts, etc.

    The 8K108058 serial number says that the transmission was originally  in a K-code car, which would make it a close ratio box, if the internals haven't been altered.  The 8K also indicates a 1968 model which ties in with the C8 casting number.  It also appears that the tailshaft has been swapped sometime during the transmission's life.

    I haven't posted much here, so hopefully this is useful.

    No K-code in '68. Last year for K-code Mustang was '67. Small block VIN codes for '68 were C for 2V 289 or J for 4V 302.

    You would have to count the teeth on the gears to determine wide or close ratio.

    If none of the internals have been swapped out, one way to determine close/wide ratio would be to remove the (4) bearing retainer bolts and slide the bearing retainer off the input shaft. If there is a groove machined around the circumference of the input shaft, at about the mid-point of its length, then it is a wide-ratio transmission. If the diameter is constant across the length of the input shaft (no groove) then it's a close ratio 4-speed. --again, this is IF the input/internals haven't been swapped out.
