So back when I picked up my '58 3800, I had to put on better wheels and tires to aid in loading it since the old tires were pretty shot and I knew they wouldn't hold air. All 4 rims that I took off are 17.5, though one is the odd man out when it comes to looks.

3 of the rims are this style

Notice how steep the lip is

Clips are held on by 1 rivet

The 1 rim has a similar yet different style

Lip is a lot smoother

Clips are held on by 1 rivet and have an extra hole for a tab

Now some are y'all might be asking why does it matter. But to me, running 2 different rims on the same vehicle just kinda bothers me lol
Also I thought about taking the centers out and have them put into a more modern size rim.

Anyone might know which is the proper rim for my truck, if either?
