ok guys, when I get to thinking about things , I usually get into trouble! I rebuilt the transmission in my 1929 two door sedan a year ago & it has not been right sense! I have read about getting new but bad main shaft & cluster bearings! thinking about going back it to see if this is the case. hear is where it gets dangerous! I am wondering if it is possible to either put 32 or later gears in my case, so it would have synchronized gears? or can I possibly use a complete later model transmission in it! can it be done & what will I get into if I try this?
