My feeling is, do not split the wishbone. If you do think that you need to do the splits, then get a later wishbone to use on your set up. The '35/'36 wishbones are really neat and should be coveted because they use the narrower axle wishbone bolts. So, all the later ones are readily available so use them.

I will let you do other searches about front end set ups to evaluate what I have said here.
