Hello,

This is a JERICO NASCAR Transmission 26 tooth ,34 spline gear . It has "26 23" stamped on it. As far as I have been able to research , this is from a 4 speed OVAL ROAD RACE VERSION , REVISION 1 Jerico transmission. I believe that this is a 3rd main shaft gear . Please see the pictures. I am not an expert. 

It came from a top NASCAR teams racers auction that I went to back in the 1990's. It has been sitting on a shelf in my basement since then. I bought a large ammount of Super T-10 and Jerico transmission parts at racing parts auctions back then. What was I thinking? Who knows. At any rate, here is a great piece fresh from a 20 year rest.                                                                                                                                    

I WILL COMBINE SHIPPING ON ALL OR ANY OF THESE TRANSMISSION PARTS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

ATTENTION: ALL OF OUR INTERNATIONAL WINNING BUYERS WILL HAVE A HANDLING FEE. TRIPS TO AND FROM THE POST OFFICE NOW TAKE UP TO AN HOUR AND SOMETIMES LONGER. WE DO NOT DO THAT MUCH INTERNATIONAL SHIPPING, THE FEES ARE AWFULLY EXPENSIVE ANYWAY. PLEASE LEAVE US A 5 STAR DETAILED SELLER RATING TO HELP KEEP OUR SHIPPING PRICES LOW WHEN YOU LEAVE FEEDBACK. Alaska and Hawaii usually cost about double. International is even more . We will ship the most economical way to the Continental US and Parcel Post to Post Office Boxes. Some shipping services have raised prices to ship 15% and more are scheduled to go up also because of higher fuel prices, which continue to go up, increasing costs for us to buy the products and for buyers to get the products. The prices of packaging materials have gone up as well, boxing tape, packing peanuts and bubblewrap has also gone up considerably in the past year.
