Hi guys out there. I need to know if the D510C coils have the same bolt spacing and connector as my D581's. I am putting a 5.3 in my Chevelle and bought some coil covers that won't work "well" with my D581's. I am wondering if I buy some D510C's if it's a plug and play thing or will I need new brackets and wiring for them?
