help with 64 dart rearend

I looked up the 7 1/4 Pinion Oil Seal removal & installation steps in my 65 Dart Shop Manual
On pg 3-17 is the removal:
1) Remove the pinion nut & yoke with puller Tool C-452 & holding tool C-3281
2) Remove the pinion oil seal with puller tool C-748

On pg 3-21 is the installation:
1) Install pinion oil seal (lip toward the pinion head) with holding tool C-3719 to space the seal flange the proper distance from the carrier
2) Install the yoke using tool C-3718 and hold tool C-3281
3) Remove the tools and install the washer (cupped side toward pinion head) and nut. Tighten nut to 240 foot pounds

What I take away from all of this is that since they did the pinion seal with the axle out of the car they couldn't take advantage of the car resting on the tires to prevent rotation of the yoke when removing the heavily torqued nut.....thus they need the C-3281 tool to hold the yoke from rotation.....If I did the job I'd try putting the car rear tires up on wheel ramps, set the emergency brake, & block the front tires to avoid that tool.....but if it looked unsafe then I'd drive another car right up against the front bumper to hold it firm. I have a manual 4 speed....with an automatic I don't know what you do.

Their tool puller C-452 is simply a heavy forged disk with threads in the center for a threaded shaft. The disk is bolted to the yoke & the threaded shaft bears against the pinion. This looks like a standard puller could be used to me.

The specialized Pinion seal removal tool however might be neat & quick but I'd probably be stuck with breaking up the seal & pulling it out with pin punch, pliers, or ??? This would go ugly for me.

On the install the position or depth the seal is installed to is controlled by their installation tool.....I think I would note the seal depth of the existing one (take pictures too) and try installing to the same depth.

I've never done this job on my 65 Dart but would guess that without the pinion seal removal tool things would slow down for me....my guess is an hour wouldn't work for my tool assortment......

If you want pictures of the manual illustrations let me know.

Hopefully someone out there has done the job & can give you an estimated time with the tools they had available

ps: got a torque wrench that goes to 240 ft lbs? My 3/4 drive torque wrench can do that but not my 1/2 drive.
