Part 120176 - Rear Cross Sills Original
You guys make great products! Every one of the items I purchased from you |fit|. No grinding, bending, filing, cutting, adjusting required. I took them out of the box, and they just fit. That says a lot! Also, when I did call your folks to talk through what I needed, they were some of the most personable people I've dealt with. ---- Thanks

If your order includes custom items, allow 45 business days. Online orders are sent UPS or FedEx ground or by truck, depending on the parts. UPS 3-Day Select, 2nd Day Air and Next Day Air are available by calling our office at 405-721-7945, Monday - Friday, 7:00 AM - 5:00 PM CT.
Some orders ship by truck freight (bedsides, 1-ton or Longhorn bed wood, strips/angles over 107 ¾", etc.). Your order will show an estimated freight amount based only on your state. When your order is received, the freight will be adjusted using the correct weight, dimensions and exact location and we will contact you with the correct freight total.
The truck freight amount collected is for standard delivery only and does not include any extra charges incurred such as lift gate service, inside delivery or change of delivery address.
You can prepay with VISA/MASTERCARD/DISCOVER or check/money order. On orders paid by personal or company check, we will hold your order 10 business days to insure the check clears before processing. For faster delivery, please send a certified check or money order. Payment must be made in U.S. funds drawn on U.S. banks. There will be a $25 charge on all returned checks. Personal checks are not accepted for orders to be picked up at MAR-K.
We must have the billing address and the name that appears on the credit card. All credit card orders are subject to authorization on amount and billing address. Notification is by mail on any unauthorized information. Parts will be shipped to the billing address on the credit card. If the billing address is a PO Box, we will need payment by check or money order.
We guarantee parts to be of proper fit. If there are any problems with your order, all transactions must be done within 30 DAYS of the date shipped. No exchanges or credits will be given until the item has been returned to MAR-K Quality Parts.

Whether you are doing the work yourself, taking it to, or having it shipped to another party, it is your responsibility to confirm that all the parts were received, and to contact us concerning any shortages within the 30 day period.
Some parts are packaged together in the same box and some are packaged individually. Some parts might include hardware, latches & link assembly, moulding clips, cross sill brackets, etc. that should be included in the package with the part, so be sure to check all boxes!
If you will be taking the parts to someone else to restore (body shop, friend, etc) it is a good idea to take pictures of the parts in the box--including any enclosed hardware, etc. Let that person know that you have checked the boxes and everything was there and had all hardware, clips, brackets, enclosed. You might also tape any enclosed instructions to the appropriate part to make it easy on the person doing the restoration. If you have the parts shipped directly from Mar-K to the body shop or person doing the work, please contact them and discuss this 30 day guarantee. Have them check the boxes upon arrival if you can't do it yourself.

If the part has been altered in any way from original state due to modification or time elapsed, it will not be eligible for refund or exchange.
Our liability for parts is only the replacement of a defective part or refund for the purchase price. No other warranty is extended or should be construed or implied. If you change your mind or order the wrong part, there will be a 20% restocking and handling fee plus ANY freight charges.
