If they had ready set parts available it would be a different part number. So with one part number they reduce part counts for distribution and what the hobby shop will stock.

Well, that piece should be the same from the buggy to the truck.

I think it is just a 4 pack...., there are 4mm spacers under the battery post but you might not need that if you use the plastic battery holders.

I'd get the rear suspension hangers and the steering rack, I've gone thru a few of the plastic ones.

Don't forget the Kyosho adjustable hangers. If I didn't have Yaiba parts already I would get these...
