Updates From Seller

Information Update (3-13-2017). We contacted Mark Williams with a serial number and component part numbers from the 3rd member. This center section is a specialty built H.E.(high efficiency) center section that is based on a Dana 60 hypoid distance. The case is designed to fit into 9" Ford housing but 9" Ford components can not be interchanged in the case. All components are unique to this design center section. There are only two gear ratios available for this design center section the 4.86 and a 5.71. Any questions, please let me know. Above Added: Mon March 13, 2017, 11:44 am EST


The item that we have for sale is a used Mark Williams 3.812 inch bore center section completely assembled with a 9.50 inch, 4.86 ratio large stem lightened pro gear. The center section has a 40 spline aluminum spool and a Mark Williams two piece pinion support. The unit has a MW-39936 - 1350 series low friction billet aluminum yoke. All parts in the assembly are in exceptionally good condition including the ring and pinion; please see the included pictures. We purchased this set-up from a local racers last year but the gear ratio is not going to work for our application so instead of tearing down a perfectly good set-up I have decided to up this unit up for sale. I do not have a Mark Williams transport container but we will throw in a use Moser transport carrier.

Asking Price for the used center section with transport container is $1650.00 Plus S&H or local pick-up is always welcome.
