Just received my 9" third member from Alan man that got here fast! Built on a Wednesday and arrived that Friday! Alan was very knowledgeable and very honest didn't try to sell me any stuff I didn't need and beat my best previous bid by 200 bucks all the parts are high quality and the gear pattern was perfect his customer service was awesome as well I would recommend anyone I know looking for 8 or 9" ford stuff to give Alan a call one highly satisfied customer!

Top notch!

Alan really knows his stuff! Received my new center section and it is a work of art! Alan is one of the best vendors I have ever dealt with, he was eager to help me in anyway he could, gave me a lot of good information, and supplied me with an excellent product! It only took three days to get my Center section! Very happy and will recommend to everyone I talk to! Thanks!

Needed a quiet one

We have a solid mounted IRS in our street rod that requires a very quiet running differential. After two "performance" shops in Arizona couldn't get the job done, we sent the aluminum housing to Alan. After just finishing a 4,300 mile trip with no problems, all we can say is ... Thanks Alan ... good job !!!
