After looking, and seeing how you're in Utah, I thought THIS guy MIGHT do you OK for the $:

Now a Word (or paragraph) of Caution:
Andersen sells chinesium, to be sure. BUT, if you want a fairly comprehensive package of parts to do over a front end, he does a fair deal. I used his wares for my first front end rebuild on our 1966 Chrysler Newport 2 door and got a solid result which held up very nicely over the first summer I drove the **** out of it, taking a crew of 4-5 adults around with me into the outskirts of Tucson on desert trails to tailer parks and huts for some political work I led the team on. This front end more or less held up right until the September the car got badly damaged in last year, excepting the lower control arm bushings. I'll never know for sure whether my own incompetence, inferior rubber or both caused those to fail after 2 years but DO keep in mind that chinese rubber is inferior, as is their steel. Indonesian rubber, by contrast, is EXCELLENT, because the Dutch imperialist assholes taught them well how to make it. Korean rubber AND steel are quite good too. Not all asiatic slave states are equal. India and Pakistan excrete the WORST stuff.....
So, IFF this job is your First Rodeo with C body front ends and/or you're really pinched for lucre, then Andersen MIGHT be a valid option. At least you'll be supporting a local capitalist if you do business with him. I won't again, but his wares are worth what you pay for them, usually.
Also, OLD rubber sucks! Old steel is GREAT if it was great when new, but organics don't age so well.
Blessings on your work
