first let me thank all of the guys on this site for their help. i am not the best restorer but i am learning. the heater unit that i bought works great. i had to drill and file and drill again but it was exciting doing the work myself. the way i mounted it was with one of the doors facing up toward the windows to use in defrost mode. this can be done without the use of hoses. i also changed the generator to an alternor and what a differce. next is a new carb, 2 sinlges and maybe a cam for my 235. if anyone has done a cam and 2 singles carbs let me know and thank you very much for your help.
