Hey microbe, i am trying to convince myself to complete the same modification on my 58 chevy apache. I have a 235/saginaw combination and an updated rear end using the patrick's ring and pinion . I love the results, but I am also dealing with the original 4 spd. saginaw. I recently picked up a disk brake kit from CPP and will install once it cools off a little ( I live in the southern california desert where the highs hover around 110). So the braking will be addressed shortly. I have been toying with the idea of replacing it with an S-10 T-5 but feel a little uneasy about completing the switch. Did you run into any real problems during the process?
