– Providing us with this sheet fully filled out will help us give you the best service possible. Even if you have detailed conversations with our Tech department concerning your job, the fact we talk to
hundreds of people over a week’s time means that we may not fully recall your specific job. Not providing us with this vital information will cause your job to sit on a shelf until you can be contacted.
– We assume components being sent for modification are in working, serviceable condition. Previously modified components may require additional labor at additional cost, or in some cases may
not qualify for a Zipper’s-engineered service or kit. If there is any question concerning your parts and this policy, please call before shipping your parts.
– To protect the integrity of the work we perform and the price structure of our kits, we cannot use parts we do not, or did not, supply in any machine shop job we perform. Unless you have Zipper’s
products or parts that were previously purchased from Zipper’s, do not send parts with your job to Zipper’s.
– Most components require some important cleaning and/or preparation steps before work can be performed. Because improper cleaning methods can actually do more harm than good, we
suggest you allow us to properly prepare your parts for modification. Extreme care is taken during out preparation process to preserve finishes. Additional charges do apply for these services.
Engine and transmission components should be washed free of oil and wrapped in heavy newspaper before being put in protective cartons. Strip down components whenever possible. Fully
assembled components such as heads sent for dual plugging cannot be re-assembled without a valve job and its related cost.
– A standard charge of $4.50 is billed to each work order to cover shop costs for chemical disposal and other materials used during the processing of a job.
– Package your parts carefully! Use plenty of newspaper for padding parts and cardboard to separate them. Heads and cylinders should be wrapped in whole sections of newspaper, placed in
individual boxes, then packaged together in a larger box with at least 2” of padding around them. Insure the boxes for replacement value.
