Thanks for the help. I have a late model swing axle. The 67 type 1 set up for the rear sounds like the plan. I will use the wide five disc brakes for the front (with lowered spindles, to get some of my front suspension back). The irony of it all is that I sold my 67 convertible cal look bug after I bought my Spyder...I had converted it to porsche bolt pattern 4-wheel discs...threw all the other drum stuff away. Luckily rear drums and hardware is cheap.
Thanks again.
