I only need a flange yolk, but am having trouble finding a driveline and was wondering if the driveline is interchangeable?

 

I would say '97 to '03 as the Heritage is left over from this generation truck.

 

I found a flange yoke on this site http://www.fordpartsgiant.com, I got tired of searching.. It was pricey but I wanted to be certain I was getting the correct part..I googled the part number the Ford dealer gave me and found it.. Allot of the other sites wanted you to give measurements and I was leary..
