[updated:LAST EDITED ON Oct-07-05 AT 08:46 PM (CST)]Hello everyone, and thanks in advance for the help. I have a 1959 Chevy 3100 Apache 235 stock, need to replace a clutch, however I like to maybe, install a three speed with overdrive or 2004r auto which has overdrive. I need to know several things, I will get the adapter to install the 2004r auto behind my 235, from Longdon’s Stovebolt wep site. My questions are what else do I have to do? Oil cooler for the trans, shifter for the trans, electric switch (12 volt) for the overdrive and do I have to install any kick down linkage? I will have to modify my drive shaft and I do have the 3.9 rear end which should work well. Thanks for the help fellow truckers.
