Chuck:
For your Kirkham, use a 1 3/16 input / 31 spline output 24" Toploader. Ratio will depend on purpose and the diff ratio you are running. In my Kirkham I am running a close ratio box with my 3:54 rear end and am very pleased..
The 24" is a short tailshaft with the shifter assembly at the end of the housing. This tailshaft housing employs an inline trans mounting pad...there is no cast in monting flange used. There is no option here... if you have a Kirkham and you are using a toploader, that's what you use.
Cal's right. Call Dave Kee and he will know exactly what you need. If you choose another source, just make sure it meets the above characteristics before you put any money down.
