74 Duster, resto mod 6.4 front end rebuild questions

So pulled the balljoints out of a another set of upper arms and threads are cooked. So before i go the tubular route i have purchased some pressed arms that run the bigger balljoint. As problem i was finding is many pressed aftermarket arms were small ball joint or a custom balljoint to work a certain brake kit etc.

Sold the old 318 and diff for 1200 bucks so happy with that to create some more space. Just figuring out who to build my 904 and then ill drop it off. About to start making the k frame dolley so can put motor in and out with box connected.
