ok so the line through the 2 pivot points if a ridgid member would give you the castor angle. correct. thats what i thought i was measuring. i will have to revisit this on google,but wouldnt the ffr piece at the top of the spindle give you that? maybe it already has an angle built in when bolted ridgid, that is what i dont know. in laymens terms and with tape measures, plumb bobs, levels is there another way i can check this that people have used?
