9 inch conversion

[flips72]

whats everyone doing about their panhard bars when changing over to a 9 inch using the stock trailng arm set up. just wondering I juiced mine out of the hole last night and broke the u joint and yoke, think its about time to change, or does anyone have any suggestions on the 12 bolt truck? it had the the 1310 u joint and a factory yoke, I was considering a billet yoke and going to the 1350 joint but was afraid of the pinion strength. my ste up is a 600hp 406 with a 150 shot on 275 drag radials and 373gear.

I put a 9" in mine with 1350 joints and trailing arms. I used a No-Limit adjustable panhard bar. It is long and goes from the original frame mount to a bracket sandwiched between the rear end saddle and shock mount. The length keeps the shifting of the rear end through the suspension travel to a minimum. works great.

I customized an adjustable panhard bar and fabricated a bracket with gusset that I welded to the opposite side trailing arm…

1972 and earlier 31 spline axles have the ability to be shortened.

28 spline axles are tapered and cannot be shortened and re-splined.

1967-1973 Mustang axles can be identified by wheel flange:
Oval hole = 28 splines.
Two large holes and counter-sunk center = 31 splines.

thanks guys for all the input, greatly appreciated. going to give the 12 bolt one more try since I already have my disc brake set up. installed a billit 1350 pinion and a 3 1/2 driveshaft with 1350 spicers maybe it will handle it till I can afford to do something different.

My setup is similar to Vins, the trailing arms were set up for the panhard and so was the c notch. I opted to try a wishbone instead.

very nice, I still have the factory suspension under mine and trying to get away from narrowing the rear end (tired of buying tires and wheels). thanks for the post.
