control arm threads/bushings

[69Tom]

So I'm presently restoring my 70 C10. I had the control arms blasted and powdercoated.

The truck was really rusty and it was a bear to remove the original bushings (upper and lower) which clearly had never been removed before.

Now upon installation, I'm noticing that the new bushings (MOOG) are difficult to turn into the control arms. The threads aren't the greatest on these bushings (they're not very deep) and I'm worried my threads on the control arms are not good due to removal of the original bushings or the powdercoaters did a number on them when they had to remove powdercoat from the threads (yes, they actually did that).

So basically my question is, how difficult should these bushings be to turn into the control arms? I've done 1 upper and one side was much easier to turn than the other, where I was using a 25" breaker bar to turn it and it's still not all the way in [was trying to do one rotation per side at a time].

I really don't have the $500 to spend right now on new reproduction arms, so I'm wondering if I should just muscle these in with the hope I never have to remove (they're certainly not going anywhere after how hard it was to turn the one side), or I really need to buy new ones.

Thanks.
