You should take a look into FS-Racing. Their stuff is cheap and In my opinion its quality.
Chassis I plan to use "chassis came with my 1/5 FSR mt", "solid as a rock"-

F-150 1/5 Body I plan to use "already have one but need another"-

The chassis I linked gives you plenty of room to move the front and rear assemblies back and forth to compensate with the wheelwell alignments. My 1/5 FSR MT was 32.5in long with a short bumper with that chassis and it wasnt even stretched along the chassis as long as it could be.
I would also like to get another set of rear and front center dogbones and cups. Their extremely reliable and their hardened steel.
