Most start with a worn out M 20-21 disassemble, decide what used parts are acceptable and re-use many worn out parts. They start the advertisement by stating ALL NEW GEARS.\u00a0If the seller does not list ALL\u00a0the new parts, you must assume the non-listed parts are used.\u00a0This strategy is to take your mind off the fact that the balance of the parts may be from the worn out transmission they started with. If you are tired of buying transmissions with used parts represented as rebuilt perhaps it is time to purchase a transmission with ALL NEW interior parts including new Auto Gear Shift Arms that replace the worn out and wobbly 50+ year old shift arms that may leak and possibly lock in gear.\u00a0I am so confident of the product I produce that I will include a copy of the receipt for all the NEW interior parts.
