looking for info on where to get these is mass quantities, anyone know of a bolt house or machine shop that carries them?

I was not going to share this... but

Here is a place I get all my stuff from, it beats the pants of the prices of the "off-road" places:

you can get

springs
spring bolts
spring hangers
spring pads
u-bolts
spindle parts
turn buckles
screw pin anchor shackles
shackle links

it is a "trailer" shop
