Wheel change

[1950 pilothouse]

I bought a set of wheels for my 50 truck. I originally had the factory steel wheels with the bolts instead of studs. How do you swap from bolts to studs since the hole is threaded?

[Plymouthy Adams]

many buy studs and the proper drill bit, drill out the thread and press in the studs....you will need to carefully measure your stud for proper knurl, head length, thread and pitch...

Would regular bolts from the back of the drum work?

seriously, think about what you just said...they already set up for using bolts in the easiest fashion possible.

It depends what you mean by regular bolts........normal hardware store bolts will be maybe grade 3............what you want are Hi tensile, fasteners........and by the time you stuff about getting them you will be better off getting proper wheel studs .........I have used various Ford studs, they are 1/2" right hand UNF threaded wheel studs..........the original mopar screw into the drum bolts are left and right hand thread 1/2 UNF, as a guide the studs to use have a 9/16th knurled shank    so you drill the mopar threads out with a 1/2" diameter drill then press the studs in from the back............what you need to do is measure the distance you want the studs to protrude out from the drum face, add the depth of the drum and hub thickness and the extra for the head of the stud......plus how thick the wheel is where the nuts fit.............total it all up and that should give you the overall length needed.....I mention using Ford studs simply because here in Oz, all local Frods use the 1/2" UNF size whereas local mopars, ie,  Valiants use a 7/16th UNF thread which is too small...........full size mopars use the 1/2" UNF size as far as I know so they may also have wheels studs that can be used..........I would NOT use ex wrecking yard studs nor would I use hardware store  or "you beaut bolts"............but your life.......lol............welcome aboard from Oz.........Andy Douglas.

Thanks! I’ll give that a try. It’s mustang gt wheels so ford studs should work

I bought my studs from a trailer parts place.  They happened to have the right length 1/2x20 studs in stock.  Measured the knurl and bought the correct drill size.  Used my press to put them in.  It can be done by pulling them in with the nut, but if one does that be sure to use stacked  washers and lube to ease the torque needed.

I just did rears on my 50 and used doorman 610-446 lug (1/2x20) bolts from the parts store, they cost under $13.00 out the door for 10 of them

Ok that’s what I’ll do. What size drill bit did you use?

[moparfun]

21-32, I used a press to install them with red locktite

I purchased the 718-8235 studs from Jegs. 1/2-20 x 1 1/2" .615 knurl. Then grab a 39/64" drill bit.
