I love Guild basses, but not the lack of adjustability of their 3 Point Bridges. I've got 4 - two B-301's, a B-302A, and an SB-202. 3 of the 4 came with some sort of metal shim beneath, one or more of, the roller/saddles, put their by the previous owner in order to try and get the action to their satisfaction.
I've found that a Babicz 3 Point "Gibson" replacement bridge can be installed without any major mods to the bass. The inserts and mounting screws are larger on the Guilds than on the Gibsons. On two of my basses, I had the inserts removed and replaced with Gibsons and then used the screws supplied by Babicz to install the bridge. On the other two, the bridges are attached with socket cap screws with no additional work required. The bridge does sit on top of the insert flanges, but, I find it to be, a vast improvement from the stock bridges. And, the bass can be returned to its original condition, if desired.
Here are a couple of pics. The bolt size is visible on the bag and I got them at Home Depot for $1.54 a pair. Also, a grinder can smooth out the ridges (on the edge) and writing (on the top) and will make the screw match the bridge more in appearance as on the Ash bass pictured.
