289 distributor upper bushing
« on: March 18, 2010, 11:09:37 PM »
I am rebuilding a hipo distributor C70F-12127-K, date code 7G26 for my motor.

I ordered a replacement upper bushing C5AZ-12120-A on Amazon.com from a Ford dealer in GA.  I ordered this part based on information published in the April 2009 Mustang Monthly.

Today the NOS part arrived and it is not even close.

The bushing I pressed out of the housing measures (in inches) 0.687 OD, 0.466 ID, and 0.715 tall. 

The part I received in the NOS box measures 0.766 OD, 0.529 ID, and 0.746 tall.

I am wondering if anyone can tell me if I have the part number right, if I got the wrong part in the right box, or if the part number information in MM is not accurate. 

Thanks in advance for any comments and suggestions.

I'm no expert but, I took a look at the FPC and the upper bushing for a C7OF-12127-K distributor is B8QH-12120-A (MC-148) The bushing you have was used in later years. Noteably on the 351W in the 70 GT350 with Automatic transmission.
The MC-148 bushing looks to be still available from Ford for about $2.
Hope this helps.

Thank you.  The B8QH-12120-A did the trick.
