On my 6.1 I had stuff in different bags that were supposed to be together. Luckily my friend had a tc 6 and told me to look in all the bags before I built mine.. I setup my 6.1 to one of herberts setups just had to put 3 deg. toe in in the rear arms. She was at 0 deg. was to loose in the rear for asphalt. handles pretty dang good on sorex 28's
