Hello there,<br />I was wondering if it's okay to use after market gears(I've heard to stay away from them),and if it is okay to replace a pinion and forward gear with after market and re-use the original reverse gear?I just don't understand why you must replace front gear with the pinion,yet can re-use the reverse gear,they run together at all times. Any views on this topic would be appreciated.<br />Thanks.............D
