i have a 36 standard town sedan it has a upside down u shaped frame with a plate rivited to the bottom. some 36 model came with a straight axle, some came with a independt front susp. they also had a frame with a c shape an a x member. 34 35 36 were mixed up with different changes on different models. i believe standard models were 109 inch wheel base an masters were112 inch that should be where you can tell the difference. a lot of parts look a like but wont interchange. jonathan
