Was this for your front driveshaft? I'm thinking I will have to modify mine for the ORD springs as I think the axle wants to drop out farther than the driveshaft will allow. (still need to complete my lift and take measurements)
Just throwing some info. out for you guy's , on my off road lifted square's, (which have a lot of travel) When I go to get the front driveshaft made I dont just get it lengthened I have them change out the yoke and the spline post as well. The stock yoke is around 6.5 inches long and I upgrade to a 8.09 inches long yoke for a 1310 joint , (you are probably get a new yoke anyway) , for more travel.
Anyway slip yoke's are cheap so why not go longer if you need the travel if you are getting a driveshaft made anyway.
On my blazer I changed the yoke on the front diff. to one that takes a 1350 joint , (stronger) , and then got my driveshaft made with a 1350 slip yoke that is 8.44 long.
Hope this helps you guy's out , and all these parts are on the shelf parts , nothing fancy or custom made.
