Company Policy


QRS products are manufactured for the year, make and model of the vehicle you specified in your order. However, we have learned over the years that there may be some variation between models in any given year. Variation could be the result of plants of origin and OEM modification during the production run of a given vehicle. Compare the new part to your original, or place it in the vehicle to determine fit and alignment of holes and contours. If you find that the product you ordered does not fit your vehicle, do not alter it in any way. Altering the product renders a refund null and void. No refund or credit will be given for a product which has been modified. Any return must be reported within 30 days of receiving package. Failure to report the need for return within 30 days may result in a $25 restocking fee per item. Depending on the nature of the return, shipping will either be funded by the customer or the vendor. Returns should be packaged in the same box as received, with the packing slip enclosed. All returns must be preceded with a phone call to QRS at (209) 942-4777.

Damaged Merchandise

Examine and count all packages carefully. If parts arrive damaged, contact the carrier immediately. All claims for damaged parts should be directed to the carrier involved (be sure to keep all packing material). Please refer to the invoice number and date on the packing slip when contacting QRS.


A Packing Slip, attached to each box that is shipped, is located on the outside of the package, and lists all items within the package/order. QRS processes each shipment using a strict inspection method. Open and inspect your parts completely, as small items may drop to the bottom of the box. If you find a shortage, please contact our office.


Telephone orders can be placed from 7 am through 3:30 p.m. Pacific Standard Time at the main phone number--(209) 942-4777.

Internet Orders

Orders can be placed On-Line through 24 hours a day.

Production Time

QRS strives to maintain a 14 day production cycle based on the date that an order is submitted. We serve on a first-come, first-serve basis. It is seldom that QRS needs to extend that time due to high production volume, and more often, we are able to ship sooner than the 14 work day quote.

Back Orders

QRS does not back order any of its products. We manufacture our products on demand. Shipments will be made when the entire order is complete.

Special Orders

Items considered to be "special" include changes or modifications to any of the QRS product line other than published by catalog, internet or advertisement. In order to accommodate your needs, an additional fee may be applied, for special order processing. Special orders must be paid in advance and are non-refundable.


All published pricing is effective immediately and supersedes any previously published catalog and/or advertised prices. QRS reserves the right to change prices without notice. Published prices on our products are for retail customers.QRS accepts Visa, Mastercard or Cashier's Checks.

Shipping Charges

QRS charges UPS Ground rates, plus a nominal box/handling fee. It is not possible to quote exact shipping charges to the customer in advance because every product/order measures and weighs differently. If a customer desires, he may choose to have his product shipped Next Day, Second day, or Three Day Air, however the cost is substantially higher. QRS will not accept the responsibility of charges when a shipment has been refused or had to be returned after three unsuccessful attempts to deliver.PRODUCTSAll QRS products are designed and manufactured based on out-of-the car/truck originals. Each product is year, make and model specific. We guarantee our quality and workmanship.

Restoration Firewall Insulators

If your firewall insulator order is for a restoration project, we guarantee satisfaction, authenticity, quality and workmanship. OEM firewall insulators "fit like a glove" and include holes punched for standard equipment. For optional equipment, hole locations are "scribed".

Street Rod Firewall Insulators

QRS manufactures all of its OEM firewall insulator products for street rod applications. These firewalls do not include any holes so that you can install only those holes that you need. We manufacture firewall insulators for aftermarket steel firewalls built by Bitchin Products, Direct Sheetmetal and other street rod body manufacturers.

Restomod Firewall Insulators

If your project vehicle is a semi-restoration/custom, QRS can provide a firewall insulator to fit your stock firewall with only those holes that you will need. Please allow extra time for custom fabrication. There is no additional charge for this service.

AcoustiSHIELD Automotive Insulation Kits

QRS manufactures a full line of automotive sound dampening and insulation kits. Each kit is year, make and model specific to a particular vehicle. Kits are designed for restored vehicles and are easily modified for custom and street rod applications.


As our customers and dealers throughout the nation, Canada and Europe will attest, our firewalls "fit like a glove". If you are not satisfied, please call our office to arrange for a correction, replacement or refund. Products which have been modified, may not be returned. (A return may be subject to $25 restocking fee.)QRS accepts no responsibility and offers no warranties, expressed or implied, regarding the safety of any of the materials used in the composition of its products other than that which is submitted by the manufacturer of the raw materials used. QRS is very selective about the materials used in production--all materials meet or exceed OEM standards.
