drive shaft swap

[slinginrods]

any body know of any later model aluminum driveshafts that will swap into swb th350 equipped 81-87?i know the 700 r4 trans shares the same yoke as the th350.but the length is different.but i was wondering if a 90s model or even newer aluminum drive shaft would work in my 84 with a th350.

so let me get this right,you have a aerostar driveshaft in your truck?if so what year and how did you get the yoke from the ford to work in your th350?or did you just use the shaft and with a conversion joint you used the gm trans yoke.sorry im a lil confused
