Speedway yokes............

Hi,if you have to buy a yoke,STAY AWAY FROM SPEEDWAYS,theirs are made in china,holes for joints are too small.i had a yoke from them machined to correct size,when i started putting the joint in,i broke the yoke,that was an almost $200.00 lesson...

no yoke needed. I got my driveshaft and yoke from a 87 mustang (AOD equipped), the driveline company told me to bring the driveshaft and they would change the u-joint flange (I think thats what its called) to match the 9 inch pinion yoke and supply the u-joints for $180. The measurements are taken from the rear of the transmission housing to the flat surface of the pinion yoke, submit them and the spit out a functioning shortened balanced driveshaft.

As for the spring perches are these the ones your referring to timothale?
http://www.speedwaymotors.com/Weld-O...Tubes,632.html Another guy said he used them on his 9 inch rear end.

Does the width of the leaf springs determine the the width of the perches I should order? Or is it one size fits all (9 inch) type of deal?

spring perch

Those are the ones,one size fits all. Most ford 9 In. use a 3 inch axle tube. early Mustang and I think fairlane with the 271 hp engines had smaller tubes so the 4 spindle U bolt air tool could torque them, the same as for 6 cyl mustangs, on the final assembly line. double check the spring center bolt and make sure the hole in the perch is big enough. If needed drill out before welding. My Brother had a fairlane he used to drag race and had the rear mounted traction bars, he used to break the spring tie bolt , after 4 replacements he drilled out the spring bolts holes and used the bolts spec'd for a full sized Galaxie.

Cool, sounds good I'm going to make the order. I hope the Chinese (Speedeway suppliers) can at least get these spring perches right. Gotta wait until this rent week is over before getting them and then I'll move on to the driveshaft. I thought it would be more involved than this. thanks guys.

I'll be buying this kit from http://www.ultrastang.com/info11.php to put disc brakes on my rear end from a Mark VII after the 9 inch is installed in place.

Well the perches came in today, they look good, I guess there's not much room for error with the Speedway perches. It turns out they got the hole size right this time Timothale so no drilling is required for this round. Next I'll be ordering the driveshaft after the perches are set in place and the appropriate measurements are made.
