Bring Your Own Parts: Agree on the Installation Before Ordering

Start with the actual vehicle and part

Send the vehicle year, make, model and trim, plus a link or part number for every item you want installed. Include photographs of the vehicle as it is now, showing previous modifications and any existing damage. A photograph of the look you want is helpful, but it is not a substitute for identifying the actual parts.

Ask the shop to confirm the application and the work it is willing to perform. A directory service tag helps you find a candidate; it does not mean the shop accepts every aftermarket part or every vehicle. If fitment is unresolved, make that a question to settle before placing an order.

Get a clear supplied-parts answer

• Will the shop install these exact customer-supplied parts? Ask about each major item, not just whether it generally installs body kits or wheels.
• Who supplies required hardware, adhesives, consumables and other supporting components? Request a list of anything excluded from the parts purchase.
• What inspection will happen before installation? Agree on what happens if the delivered item is damaged, incomplete or does not match the agreed application.
• How does the shop handle a parts problem separately from a workmanship concern? Ask for its written terms for this specific job rather than assuming the parts seller and installer cover the same things.

Arrange delivery with the receiving shop

Before shipping to a business, confirm the receiving address, contact person, delivery hours and whether the shop can accept the size and type of shipment. Ask whether it needs the vehicle present when the parts arrive. Agree on how the package will be identified and who will report a visible delivery problem.

Do not assume a listing in this directory is permission to send a package. Wait for the receiving shop’s agreement and keep its instructions with your order record. The shop should also explain any storage arrangements if the parts arrive before the installation appointment.

Approve a scope, not just a date

Ask for the estimate to distinguish inspection, preparation, test fitting, finish work and final assembly where relevant. If the shop discovers additional work, agree that it will describe the change and obtain your approval before proceeding. Use the quote-comparison worksheet to check whether two shops are quoting the same result.

At collection, compare the finished work with the written scope. Keep the final invoice, part identification, photographs and any care instructions together so a later question can be traced to the actual installation.
