My advice is don't. You'll be money ahead getting rid of the total loss car and taking that money and the fortune you would spend to resurrect the car and just buying a good used example.It was very unfortunate but my 2018 Hellcat charger has been deemed a total loss with that being said I am looking to rebuild the car the chassis is pretty damage so I will be looking at buying an older charger to strip just wondering what year charger would be the best for that would it have to be a 2015? or do the older chargers have the same bolt patterns and such on the chassis? This is going to be a really big project for me and any insight or tips would be greatly appreciated
If you want to go ahead my advice is to try to get a parts car the same MY as your car. The same MY or a car in the same basic model run. For instance a 2015 to 2017. IIRC Dodge did an update on the 2018 car. The closer you are to the same MY parts car the more likely parts will interchange.
Also, search YouTube for videos of Hellcats being rebuilt. There are several. Watch them all to get an idea of what you are facing.
