If I recall correctly it will work on a D1 but you would need to swap out the transfer case output flange.

 

What's the new code or is the special gone for forum members and $208 the standard price now.

 

I called and asked this morning.
No code at the moment, but they still give the discount.
I thought their prices were good, especially compared to the competition...then they knocked something noticeable off of everything I bought, including the front driveshaft.
I haven't checked my invoice vs the website prices, but the discount was big.
The service was excellent.
I am Very happy that I called them! They have my future business now too.
