For those that have done this the hardest part is getting the old king pins out of the axle as the old grease and other crud will hold them there but there are a few other traps for new players in the reassembley process.

I have stumbled through this process a few times. I don't think you will have any significant problems. Once the bushings are pressed into the spindles, you will need to ream or hone them to fit the pins. Good luck.

I agree that the most difficult task is getting the old kingpins out of the axle. I have done 3 sets and that was a real issue on 2 of them. We had to take both of them to a machine shop so they could use their hydraulic press to remove them. Heating with a torch did not help on one of them.
The other advice I have is to remove the axle from the vehicle. It only takes a little more time and really gives you the access you need to do the job correctly. I made a simple fixture that fit into the end of my floor jack. It holds the axle upright and prevents it from rotating down (flipping over) when you remove the axle.
Check your shop manual so you get the correct reamer. You can size the bushings with a hone but it really takes a lot of time.

I could not find anyone to do it so I got the correct king pin reamer on ebay and did them myself for my 31. Make sure it is a king pin reamer as the bushing have to be reamed inline with each other.

Dave is giving you great advice. The proper kingpin reamer is long enough that it will ream the lower bushing in line with the upper one.

Keep watching eBay.

Join VCCA and contact the 1933 Technical Advisor plus members in your close-by regions.
Take the axle to a machine shop and let them set it up on a machining center to size the bushings.

A machine shop can do this at a reasonable price. I had mine honed to size and had a very nice lasting fit.

Why would the .736 be listed as the correct one if it is too big?
