ISO driveshaft 7290

I sent my driveshaft to dynamic drivelines in Des Moines to be shortened and have a 7290 tube yoke welded on (instead of the 7260) and 7290 30 spline slip yoke installed. All they did was shorten it... no new 7290 tube yoke, no 7290 slip yoke. Hell, at this point I doubt it's even balanced it.
They NEVER answer the phone so I can't even call them to ask any questions.

So I'm looking for a driveshaft with 7290 on both sides and a 7290 30 spline slip yoke for 727. 44.88 length would be perfect.
TIA
