ok i am thinking about doing a SOA on my 74 fj40. my question is about how to get the front pinion angle right. my idea was to set the ale on block with the spring perches flat on the block then set the new perches on top, make sure they are pefectly level then weld them in place. will this work? i am going to try to get some fj55 springs to use but will prolly have to use the stock springs for now any feedback would be appreciated
