wtb: Driveshaft for 65 dart 273 4sp 8.75 trunion

I'm switching out my 7.25 rearend for a 8.75 in 65 dartcharger 273 4sp.
Need a trunion style driveshaft for a 8.75 rear end.. trunion style was only used on the 64 -65 early abody. or if someone has all ready converted it over to a better style front u-joint. ..I do not have any mesurements of that driveshaft length for the 8.75 rearend.
I think 65-65 barracuda had the same wheelbase as the dart too >>> that driveshaft will probally work also.

or does anyone know if the two driveshafts are the same length for 7.25 and 8.75? v-8 cars 4 sp.
Let me see what you all have . Thanks !
