Hello, I have a 1921 Studebaker model EJ touring car that does not have the original distributor. As a matter of fact the one in the car is cracked and ready to fall apart soon. I need help in identifying the original model. Does anybody have a 20's reference book as to help me identify the original one? I have found a model 639 on ebay that has the timing mechanism and I may be able to retrofit to the car. Also, I was wondering who you could recommend for distributor work? Thanks, BBStude21
