Extras on a vehicle cause game to CTD, but they work on a different vehicle

So I need some help with something that's getting really frustrating.

I recently started working on making an SAHP Declasse Alamo 2600LS that I want to release in an SAHP minipack I'm working on. All the work I've done has since been successful, but now at the very tail end of the mod work, it's having trouble. 

So, I've pulled the majority of the parts (antennas, bullbars, puck antenna, and black box) from Pumpk1in's SAHP Buffalo SX onto the Alamo 2600LS (original car model is by IlayArye, but I pulled the police version by Sgt_Jhonny). Once I exported the car and attempted to load it into GTA, it crashed to desktop. Of all the parts I transferred over, I found that the issues were being caused by the puck antenna, and the black box, because the car works with no trouble when I don't have them installed.

I don't understand why they aren't working, because the other antennas and bullbars work fine. Additionally, they also work with no issue on a custom SAHP Scout I made as part of this pack (based on Nacho's 2020 Scout).

I have them set up on both cars as Extras, so there shouldn't be any issues to the puck and the black box, but the Alamo crashes the game whenever I try to load it in. Does anyone know what causes this, and how do I remedy the issue so I can make my minipack work?
