this calculator is under development.

i am planning to it.

(insert one of the verbs below in the blank above)

improve, modernize, update, ameliorate, reform, rehabilitate, recondition, refurbish, renovate, rejuvenate, overhaul

until then you can use the old wheelguide, which is really meant for 68-70 Dodge Charger owners.

or use some of my other calculators.
