9 inch ford

I put a 9 inch ford in my 73 dart, just wondered what guys are doing with driveshaft, do i have to get a new one made or are there adapter u joints available. Its a 318 with a 904 trans
Thanks for any info
I put a ford 8.8 under my dart..go to DennysDriveshafts.com and they have all the universal parts you’ll need to complete the swap.
