My caster mod (with pictures)

[crakarjax]

I'm mocking my parts up to do this mod but it looks like my lca only has .5" before it will hit the saddle during travel. Tons of space everywhere else, just the part of the lca that kicks out will be hitting. Has anyone run into this? The suspension is stock '72 so far.

Another angle. This is slightly past stock bumpstop travel.

I shaved that inside portion of the arm to get clearance to allow moving the arm forward .750".

Thanks, I guess I'll go for it. Trim until it fits seems to be the consensus in general...

Ok I just went and tried to drill my cross-shaft... what kind of drill bit are you guys using? I didn't even make a dent. I have new TRW cross shafts and they seem to be made of a metallic form of diamond.

When I had mine done, I took them to a friend's machine shop and we chucked them up in a lathe and used a flat bottom carbide end mill. A local machine shop would not charge you much to do this. A standard hardware store drill bit set isn't hard enough to drill the hardened cross shaft. Plus, using a mill is much more precise because you can lock the shaft in the mill and get the new pin locations located exactly.
