Rick this is the best I could measure:
c/L pin to c/L of first column of bolt holes. 17.5"
c/L pin to c/L of second column of bolt holes. 25.75"
and the width of the box. 12.0"

It seems very close to the L05 Lippet 1621 on the earlier link so I think the real measurement are:

c/L pin to c/L of first column of bolt holes. 17.75"
c/L pin to c/L of second column of bolt holes. 25.625"
and the width of the box. 12.0"

I have one for sale off a Landmark if anyone needs it. Used from the factory to the dealer. Installed a Fifth Airborne which works great.

I am looking for a MOR/RYDE or a TRAIL-AIRE. Thank you though. BTW how do you like the fifth airborne?

The Fith Airborne is the best thing we have added, right next to the Trail Air on the 8K axles/springs. Only towed it around 2000 miles but it really works well with no noticeable chucking.
