That's just way too much money for what is there.

Here's my breakdown of the parts. These prices are standard, look them up on the web.

Cromoly Tubing - $18
Steel Stock for Tie-rod mounts - $20
Spherical Bearings - $52
Retaining Clips - $8
Shoulder Bolts - $8
Washers - $4

5-7 hours of machining, welding, drilling at $50/ hour.

That's $110 in materials and $250-350 in labor.

I don't see where the remaining cost is coming from unless it's purely markup.
