When dealing with our 50 year old cars, it is often hard to tell what a previous owner may have done, so you have to do your homework.  If the 5th digit of the VIN for your 65 car is a "T", the car was built as a 6 cylinder car.  If you have an A,C, or K as your 5th VIN digit, it was built as an 8 cylinder car, and would have had the 5 lug hardware up front (and out back).  If you have a T code car, and 5 lug hardware up front, someone has changed something, and you need to know what they have done, if you are thinking about changing something.  Someone may have installed later vintage Granada spindles, etc.  If it were me, I would take off a front wheel, make a CLOSE inspection of the spindles, and write down the Ford part number in the casting of the spindle, and report the number back here (or do a Google search of the part number) and we will help you identify what spindles you have.  There is a lot of knowledge here at FYIFORD, and guys are really willing to give you all the help you need.

If my memory serves me well, the part number is cast in 2 lines on the engine side of the vertical part of the spindle, between the upper & lower ball joints.  It will probably be hard to read due to 50 years of exposure to the elements, but get what you can.

rocklord correctly states that the V8 spindles are beefier, and JKB has posted a picture of the 65/66 V8 spindles (with hubs) he is selling in the Swap Meet section of the forum, if you want a pic for comparison/reference.
 
Welcome aboard!

Thanks for the responses I really appreciate the help.  This car has been a labor of love for about 7yrs and is finally nearing paint.  I'm getting to the point of doing the brakes and need to order the mustang steve front kit no, and wanted to verify spindles.  I'll get the numbers and check back.

I cant find my part number on the mustang tech page.  my drivers spindle is  C5DA-3107A  I can find B and C but not an A
 

The spindles above are 67-69 V8 spindles.  Same were used on I-6 and V-8 cars.  They were used for drum and disc brakes in 1967 and drum brakes only in 68-69.  Note the vertical sides of the part around the 4-bolt pattern are inset.  The 67-69 spindles use A2 and A6 bearing sets.
The 70-73 drum brake spindles appear identical but have a larger diameter axle, using A12 and A13 bearings.


The spindles in the above pic are 64-1/2 to 66 Mustang V8 spindles used with five lug drum and disc brakes.  Note the sides of the part around the 4-bolt pattern are straight.  They use A2 and A6 bearings.




64-1/2 to 66 Mustang I-6 spindles are similar but have a smaller diameter axle and the radius arm is straighter without as much downward offset.
