ok, wow driveshaft length chart problem

Rani, why not measure what you have and compare it to what the chart says.

52.70-51.89 = - 0.81"

Average = 52.295" (or a tad over 52 1/4")

You're only talking a little under 1" difference. With the length of engagement of the slip yoke in front, it may be close enough, or take the average of them. See if you have one in that range, then when you put it together see if it fits. If not, then make an "adjustment"...
