We charge $450 JUST TO PROPERLY ALIGN A TTB FRONT at work. No parts replaced or springs repaired or anything. We even have a custom spring shop within a few miles and its still way cheaper to swap a used 60 in.
$450 Just for an alignment? My local guy only charges $80 to do the alignment. He said he'd do the alignment and tie rods for around $170, with me supplying the parts.
I gave Betts a call, but they said for my truck it would have to be a special order and they didn't have the information for it on hand when I called, so that's a dead end for the moment.
I also called SD Springs. From them, the springs are about $120 each. For both sides, plus hardware and shipping out to California, was around $420 (I forget the exact amount). Damn that shipping hurts!
So, right now I'm at around $200 for the tie rids, $400 for the springs, and $200 to put everything on and align it. Considering the only D60 I know of offhand is close to $2k before seals / bearings / tie rods / etc, a D60 swap ain't that cheap.
If I can come across a D60 for the right price, I'll jump on it. For the time being though, my D50 doesn't need a rebuild but it sure could use a bandaid or three.
I'm on mobile right now so I can't reply to everyone very well until I get home, but thanks to everyone for the input thus far, keep it coming!
