CORE RETURN POLICY
The definition of a good rebuildable core is as follows:
1 Your unit must have all parts and must not have rust so much so that your core can not be rebuilt. 2 Refunds take about three weeks from the time we receive your core. We must receive your core back within 120 days of the date we shipped to you for a full refund to be applied. You will still receive a refund of 1⁄2 if we receive your core after the 120 days and it’s rebuildable.
3 You will need to fill out and return the your portion with your core return.
---------------------------------------------------------------------------- DATE SENT_____________
Please cut on the above line and return with your core.
I have read the terms and conditions of the core return policy and agree with all conditions.
