I think I want the zzp dual pass end plate but I also want the option b. Can I buy the option B from CED and it still run like it should with the refurbished zzp end plate? I am thinking about getting a shop to do it here for like 200 bucks (55 dollars an hour). Overall that would make my cost about 359 instead of 640. ( i have a 70 dollar coupon for zzp also).
