i am in the extremely slow process of soaing my 74 fj40. i was in the garage this weekend and i noticed that you can take the third member out flip the housing 180' and put the third member back in and it will bolt up the same way as if you had welded on new perches. i know there are a few things i need to do other than just new perches(shock mounts, pinion angle etc.) but my question is if i fab up a anti-wrap bar should i be alright with the stock perches and the stock drive train?
