I wanted to throw this out to those with more knowledge. Are there any advantages in using the C-body spindles as opposed to the late A-body or FMJ units? Firm Feel has some nicely made C-body drop units now and am wondering what the advantage would be over the others. Also, any difference in brake attachment, ball joint hole size, bearing size? They do offer dropped A/E/B body units but am not sure if those are offshore cast. Thoughts brethren?
