A little history on the RC bought it almost 3 years ago bent a dog bone and never fixed it and that's how its been ever since got maybe 8 runs on the engine and I made sure to put some after run oil in the engine every so often over the years. I want to get it running again so I decided to finally fix my savage x 4.6 and I've always wanted to do the conversion to xl length and width but now I cant find certain parts like the "xl tvp 3mm chassis" and so forth online. if it isn't possible to do anymore is there any other conversion I can do to get the xl size. Any and all Info on my subject is welcomed and if you can point me in the right direction for the parts I need that would be help too.

Thanks
