Rotisserie question

I just found a used rotisserie for my 68 Valiant resto and it has no additional attachment brackets. It looks like a CR300 model witch looks like a common type unit. Can anyone confirm the best brackets for an a body? I am seeing leaf spring type for rear and a uni-body
type for the front. Any advise would be greatly appreciated. I will be ready to put the car on the rotisserie in two weeks!
