Bosscat questions

[Peakey]

Hi everyone

I'm fairly new on here and I have a few questions. I have just bought a bosscat that is well new in the box all the bits are there but it isn't completely built and by the look I it all the bits are there minus the shell but that's no big problem.







So to my questions. Reading in the manual it refers to pro parts are these as standed or not as for example the pro diff ect?

And should I get it running or build it and leave it on the shelf?

Thanks for the help in advance
