69 GT350/500 Front Spindles

Hey to a G.T.500 owner.In regards to your question about spindles,you should have the large bearing type if the car was produced after 04/17/69.If this car is to be driven and may see track time-go big-if it is a show only car keep it stock.We have seen cars break the small type of spindles.In either case have them magnafluxed to ensure no cracks have developed.It is cheap insurance and well worth it.Ford claims that the wider 15" wheels put added stress into a part that was not designed to handle that type of load.Lots of info in the BOSS 302 book by Donald Farr,and well worth reading-it may contain casting numbers as well.
Good Luck

 

No they were meant for the later - larger tires. The whole date thing is in discussion but considerign your date of build it does not concern you

Since you don't need them, we'll save you some money (read approx $500 for two rotors) all you need is the standard Mustang ones and the bearings to go with them

 

Believe that would (along with the E70 x 15's) would be what would be expected. The suspension change was all about the need to support the new wider tires.

Just noticed your signature - any pictures of the car? I'm almost in the middle of a 69 restoration - lots of pieces.

Opps. The owner of the car I'm helping will already ponied up and bought a pair.

 

The early 69's got the C8 spindles and the later after 4/15 got the D0 marked larger bearing spindles. To add to the puzzle I have owned few early 69's built in Jan that had DO marked spindles and have seen a couple Of 70 GT350's with KK marked Boss 9 spindles.

 

Yes the spindles are a mess - My 4/69 Boss has one KK and on D0 spindle and the 5/69 350 We're doing has KK on both

Don't mean to confuse the issue more
