Anyone know of any web sites that has lots of springs? Been searching for weeks with no luck. Any help would be great.

Ebay sellers have a few but by part number, not model.
Type 'brake spring ferguson' into search.
I'm sure you looked there though, but that's all I know of. One of the sellers seems to sell nothing but tractor parts so you could ask him, or ask Massey directly.

Thanks for the information joypulv, will check it out.

Let me google that for you (http://lmgtfy.com/?q=%27brake+spring+ferguson%27+) This seems to produce several helpful links for you to follow up on.
