Hello,

It will depend on the belt routing and position of the compressor.
What size engine does your 300 have? 2.7L, 3.5L or 5.7L?

Since there was no factory option without the A/C, there is no size listed on the catalog.
To find out what size belt you need, you will have to use a string/rope and route it just like the belt would have, just don't go around the A/C compressor. Then measure the rope to find the size that you will need.
If you can route the string without it touching the AC pulley, then you can install a belt safely. If it touches the AC pulley, then the compressor must be removed before installing a belt to bypass it.
