'69 Mach 1 Tailshaft

[simo]

Hi Guys, does any one have a tail shaft for a 1969 Mach 1 that they would like to sell ? Not sure if they're all the same so the trans is a C6 auto with a FE 390 engine.
Many thanks,
Simo

That might be a hard find . You can buy new C6 slip yokes and then get a tail shaft made or a used tail shaft from a C6 from a ford and get cut and shut / remade .  Might cost around $ 800 From scratch tho .  Count the splines on the output shaft on the box 1st even tho it should be 31 ,but you never know .

Track down a bloke known as Mungus on this site or the other Aust Mustang forum. I gave him a tail shaft for a 390 and a C6 a few weeks ago. He may be willing to part with it. Mungus lives about an hour out of Melbourne.

Mungus lives about an hour out of Melbourne.

His name is Hugh and he's in either Ballarat or Bendigo - can't remember which...

Yup that's me. I live on a wee farm near Riddells Creek ("Just Mustangs" owned by Russell Trainor, is about 6km West from me). I've PM'd simo already. Sadly that S code shaft is needed here and I finished restoring it last week. Took a while...   

I passed on my recommendations stateside (Dead Nuts On) and locally (Duggans). Hope he gets one. Shouldn't be too hard. C6 yokes are an off the shelf item and not expensive. All just depends on how much one wants to spend. $340-550 USD plus post for a D.N.O. concourse or uprated shaft, and that will be spot on looks wise (if that's what one wants). They sell yokes too, including OEM ones. Lots of driveshaft places will make one for you, but probably using aftermarket flanges and painted black with washers for weights etc.

Mine is about right for most 67-69 S code C6 cars so the concourse judges tell me. Assuming that's one someone's aiming for. Apologies for the crap iPhone photo.

My C6 is OEM and I also have a 1972 F150's C6 as a spare and they both have 31 spline output shafts.
I ran the MPC and most share the same output shafts so thinking a 31 is the way to go.
Likewise it seems the 67-69' 390 / 428 driveshafts share the same PN's (2 varieties though, straight 3" and tapered 3-1/2" which I’m told were used on CJ428’s)
So it shouldn't be too hard to find the flanges to make one up. If you come up short locally there are a couple of speciality shops in the states that have the exact right ones. They use common 1330 U/J's: which are cheap and easy to get locally.

Small point about using 2nd hand shafts, apart from rust etc the other thing some don't know is that most 67-70 Mustang shafts had a cardboard liner for sound deadening. Like a big poster tube. Some break down with time (I cut one up that was being binned out of curiosity, and the cardboard was on its way out). When that happens it affects the balance. So unless it looks really schmicko I'd be a bit wary of running an unknown 50 year old shaft with big HP or at speed. Places like Duggans will whip you up a new tube and balance it spot on for reasonable $$. And they are Mustang / Ford guys from way back. I think Warren still has his Mach 1...

Heres a few photos of one of a C6 slip yoke after cleaning.

Thanks for all the info guys, it's been a huge help as I wasn't sure where to start. Hugh , many thanks for your PM's & pic's on the thread . I will be giving Duggans a bell & get the ball rolling asap.

Small bit of info for when buying your UJ's. It would be a bummer to install the wrong 1330 UJ in the rear of your shiny new shaft...
Both ends use a 1330 UJ however the rear one has mixed bearing cup sizes. Its the same set up Ford OZ used on the old Falcon GT's.

The front has both sides wearing 1-1/16" bearings. The aftermarket PN for the front one is RUJ3002.
The rear has the driveshaft side with 1-1/16" bearings and the differential side wearing 1-1/8" bearing cups. The aftermarket PN for the rear one is RUJ3000.

A photo of the OEM rear UJ box is attached.

You can usually buy the pair locally as a kit for not too much.
I bought my last set off this bloke. Japanese Toyo, with zerk fittings. No doubt there are others.

Just wanted to give a shout-out to Warren at Duggan's. Just decided to get a new DS made for my 70 Mach 1 to fit my Toploader, great price and a 3 day turnaround. He really knows his stuff, great fit and detailed measurements.
