The tool numbers that you mentioned are not Dodge specific tools..they are numbers that Dodge gave those tools. I have rebuilt many carbs without tools out of my tool chest.
A couple notes of caution.
Many carb rebuild kits listed for the PW are actually for the M37. They work just fine except fox possible differences in the accelerator pump. Just check to see if the new accelerator pump rod is the same. If not, swap parts to make it correct.
Also make sure that the new main jet is the same size as the old one. I am talking about the diameter of the hole in it. I have found that many new ones have a smaller diameter and will cause the engine to run poorly unless you pull the choke slightly. That is due to a lean condition due to the smaller main jet. I spent hours fighting this one. I put the old jet back in and it ran just fine. There is really no wear in these jets. If I remember correctly the carbs without tools the governor require the larger jet. You can use a numbered drill set to check the jet’s diameter
