Did i screw up?
Hi:-)
I am swapping a 9" in place of the 44 rear in my 48.I cut the 44 completly out.I have a complete rear from a 70 F100 and the funky shackles dont look right under there or do i like the perches.
Am i suppose to bolt the 9" to my 48's springs?Should i have left the springs?
I appreciate any info.I checked the search engine but didnt see what i needed.
Thanks!

Let's just say there are several ways to skin a cat. You can replace shackles, springs, etc like you've started to.
When I put a 9" under my 48 I left the original springs, bought 3"x9" U-bolts at NAPA, scrounged around for a new plate (used one from an 85 but could be just a flat steel plate with 4 holes to fit the 3" axle and the 2" springs). The U-bolts will be upside down compared to the original application. Oh, I needed 5* caster shims on the spring perch's to rotate the pinion down to match the tranny output shaft, but that depends on what 9" you use.
If you didn't destroy the original spring brackets you could bolt them back on the frame. I'd use grade 8 bolts.
Good luck!

you can go to speedwaymotors.com and get bolt on perches. You'd have to drill holes in frame to mount them . That's what I'm going to do on my "49". I have to move rear forward for my shortbed.

Thanks guys.
Tim,
I didnt destroy the perches at all.I split the rivets with a cut-off whell thaen air cheisled them through.
Have you ever seen a 9" with the later truck springs/perches on one?
I centered the axle and didnt like the way the rear shaks looked.
Now the biggie:
I am going to use 3 inch lowering blocks.Think i can mount the 9" on the orig springs and find the 2 to 3 extended u-bolts?
Thanks.
I had already planned on grade8's if i go this way.

A good spring shop should be able to make any size U-bolts you want. Check your local shops for the cost.

I know what you mean about the later spring shackles - I have a 73, 77 and an 86 that all have stock 9" rears. All have the springs mounted on huge brackets that would look out of place (my opinion) on the '48.
When I got my u-bolts at NAPA all they needed to know was the axle diameter and how long did I want the bolts to be - with 3" lift you'll want 11 or 12" bolts. No wonder you need to hide the brackets
I always wonder if my mods are as good as stock - I don't recommend this kind of test, but it does say something about what we're doing. In July I was rear-ended by an F-250 4X4 extended cab. The collision spun me 180* and dropped me into a ditch hard enough to bend a wheel and axle shaft. Damage to the box, cab and frame came to $4,000 on this '48 daily driver. Even broke one cast iron waterpump foot from the wracking the frame took. [flathead V8 has 2 waterpumps - one for each half of the block that also serve as motor mounts]
The 9" rear setup never moved thru all that. The truck is back on the road this week - not finished, but primer will hold it until spring. We do good work!
