Hmmmm...

The kit looks complete, but I wonder.... Have you priced-out the same parts at your local autoparts store?

On my '71 Charger, I replaced the front-end parts in 2000. I don't recall the total parts bill as being that high ($254 plus $22 for shipping) but then again, it was 7-8 years ago.

It was do-able, but there were challenges, like getting the torsion-bars dislodged (they make a good clamp-tool to remove 'em with a sledge-hammer) and pressing the lower-control-arm bushings out of the arms was no picnic either.

A giant pipe-wrench came in handy for unscrewing the upper ball-joints (though some are "press-In" type, mine were threaded.)

I media-blasted all the re-usable parts and painted/repainted.

A Factory-Service-Manual comes in handy too.
