Not the same the holes are slightly different thats why everything sits slightly lows I've converted my first savage to an x so I know there are little details that are different ever the diff and skid plates a different. Its a lot more works to convert than you would think.
It might be but its have the old school TVPs and roll bar which would mean it have the old school transmission case and radio box. I could be mistaken because there is not a side pic but it does look like a 21 or 25
I have a few RC Trucks but I really miss my savage so if you have a Roller or an almost ready to run let me know I really just want to spend around 150$
