DADS50,
Looks like your 50 is using the 2 split mounts style which all the vendors sell for a 50. I'm wondering if mine should be the same. Comes close to fitting with the 1 center mount style too. I feel like I hear some have used the center one too. Per your diagram hopefully all the shims is only the setup for a big truck, mine would be way too tall over the fender mounting holes if I used those.
