Front x-member upper A-arm shaft studs, where to get?

[BubbaGreen]

as you all know, I am pulled the front
cross-member out of my truck to rebuild and
clean up. Well I have questions now.
First off, I did NOT put the motor back in,
I loosened up the lower ball joints and left
the nut on with a good sized gap and broke
the ball joint free from the spindle with a
pickle-fork...anyway, there wasnt much tension
and the springs pretty much just fell out on
there own (no force)...the truck sits level,and both springs are the same height, left and right anyway...Should I replace these? They are probably original, so who
sells GOOD ones, where should I buy?

Second big question is, the drivers side upper
A-Arm shaft retaining studs looks like they were
cross-threaded (yes BOTH of them)...These
look like they're pressed in, does anybody
sell new ones (they are grade-8, by the marks) PLEASE HELP!
Thanks.
