stupid spark plugs

[MR_MNZTR_SY]

i was at auto zone getting new plugs and forgot the CORRECT number and looked on their computer and saw the CR43TS plugs fit and thought thatl looked familiar so i bought em. got home and jsut double checked on the FAQ to be sure and of course i got the wrong plug :evil: is there any seriously debilitating reason that this plug is incorrect or do i have to make a return trip to autozone?

also, als propshaft came today, looks great cant wait to get it in the truck :lol:

Return 'em, get some NGK UR5's from a Napa dealer, or Advance Auto, or somewhere else... all the Napa dealers local to me in Carol Stream seem to carry the UR5's.

How much was that propshaft??

thanks for the plug info, auto zone didnt have them so i just bought what they DID have. i wanted plugs for after i ran the TEC and changed the oil, obviously i had to keep the old plugs and the truck runs really rough, should be able to get to this today or friday. stupid things like this piss me off so much.

anyway, the propshaft is 490 before shipping and was something like 507 or 517 or something after shipping depending on where you live. its not the cheapest way to go but it is probably the smartest way to go.
