Yes, most likely - just have him measure the bolt pattern on his flanges and it should be the same. The Dual case setup is exactly what it came off of!
I am in the process of putting parts together to do a SAS on my 92 pickup. I know I am going to need a custom front drive shaft but not sure what my measurements are going to be yet. I will be putting a 79-85 toyota front axle under it. Do you know if this driveshaft will work for sure on what I am going to do or is it best to wait until I have it all together to get my measurements first?
It will most likely work perfectly if you are going with Dual Transfer Cases. It is set up for the stock Toyota Drive Flanges like your Toy Front Axle will have as well as your Transfer Case.
At the most it may need to be shortened which is very easy and relatively inexpensive for a Driveline shop to do and still save you a ton of money compared to having to buy new.
