Darcy,
Buy yourself a load of Johnny joints and build your own.
Uppers require 2", and lowers require 2.5". Thats mounting width. 2" only come with 1 shank size, and 2.5's have either 1" or 1.25" shanks. Im fond of the 1.25's.
You can tap heavy wall tube, or purchase inserts from various shops. Evo makes good inserts, and are local.
In the end, that wont be a ton cheaper then buying other aftermarkets, but what you are left with is a full set of arms that are stonger, better riding, and lower maintenance then any other aftermarket arm on the market.
Feel free to stop by sometime and I can show you a bunch the different joints and recipes I use for them.
Robin comes by to help all the time. If you want to come by, just hook up with him and make a trip into town.
