A few notes about our Classifieds

This is the latest, greatest update to the classifieds page.  We have many more parts available than in the past.  Most of what we are offering are  Hard-Core Racing Parts.  We only sell parts that are in good useable condition.  In many cases, we obtain these specifically for selling on this page, in other cases, these are parts we no longer use ourselves.  IN ALL CASES, we check the parts and offer them for sale as shown.  We try to represent them in their actual condition and try to offer pix wherever possible.  In almost all cases, the prices shown are almost exactly half of the original MSRP of the parts.  We feel this is extremely fair for parts in good to excellent condition.  Parts that are a little further past their prime are priced accordingly.  In all cases, I may be willing to dicker if WE feel the price will be mutually acceptable.  It doesn't hurt to ask.

This page will be updated at least monthly so e-mail if you see anything you are interested in.  We accept CREDIT CARDS, Paypal , MO and personal checks.  I ship immediately on CC, Paypal and MO's.  Personal checks take 10 days to clear.  I can ship anywhere via UPS ground.  Shipping charges are extra.  A note about Paypal ; Paypal has fees associated with the use of their service.  These fees amount to about 3% of the transaction.  You, the customer, does not pay these fees, I do as the merchant accepting the transaction, credit card or cash.  I will accept and pay the fees up to $200.  Over that amount, the 3% must be added to all purchases.  Your satisfaction is our guarantee.  If you are not happy with something, return it for refund minus 15% restocking charge & shipping charges.

Don't forget to check out the Carb & Manifold section.  We offer for sale new & rebuilt Mikuni carbs and parts.  Most all manifolds are going to be Datsun /Nissan related.  We have setups for both 4 & 6 cylinder L-series cars.  We also do rebuilds and competition modifications to your Mikuni Carbs .  Ask us for a quote.
