    After my 3rd c6 I am ready to try a 4speed. I need a list of everything needed to do it. Anyone done this on a 68/69 FE ? Also any source for the parts will help. I have tranny, bell housing, pedal assy and shifter minus the handle/stalk.. Its all the little stuff I'm not sure of. Any and all help appreciated.

    I've been collecting parts to do the same on my 1969 GT S code a 4v 390... (it currently has a C6 & going to a period correct toploader. Not sure of all the differences from 390 to 427. maybe the bell housing, # of splines, & clutch for the additional hp & torque. Have not done the transfer yet, so can't tell you the list is 100% - but, am thinking my list might be a good start... Let me know if yo want a copy of my spreadsheet?
