They'll be KF parts.. KFactory
If your JS has the narrow rear end then it's a different rear bulkhead and bottom plate.
Here's a list of changes the TM 502 series had
Front bulkhead changed twice, from bottom inserting diff to top mount
Steering changed twice from rails, to rack to bell
ED system changed the internal gear ratios Trans and front pulleys as well as the 2nd gear housing.
The clutch changed three times, non ufo centax small, ufo centax and back to non ufo centax
Top cross brace support ( and bulkheads) changed twice from origi to top mount, to WC
Front bumper top plate changed to support WC
Chassis plates changed from wide front G4+, to RS narrow front in various thicknesses
Shocks have changed a few times, top mount etc. And piston shafts ansd securing method, holes, bladders.
Shock tower widths
Rear hubs changed and top arm methid
Flying wing arms were added and rear sway system
Disk brake system and hub for pulley support varies the latest being a non ed lightweight with pins.
Radio module box changed from early models
Ive probably forgotten lots of other changes on the 502 series.
But for the most part your late model JS kit is best hopped up by buying a G4+/EVO 08, and then all you need is an ED transmission system. I wouldnt suggest individually hopping it up, it'd be cheaper buying a second hand or new G4+/EVO
And in my honest opinion.. the G4+ LE is and was by far TM's best car
Here's what our race car spec is comprised of
+ WC kit (Front end only)
+ G4+EVO shocks
+ ED transmission
+ Wide shock tower rear
+ UFO clutch
Im going to try and post a lot of old and used spare parts on my website over the coming months to help out people with hand me down TM cars, they'll be $1-5 dollar parts and am happy to help out anyone with needs such as yourself as I have too many TM's and parts like many of us do.
The problem with the belt tensioning is that the whole rear end needs changing if you go backwards in chassis plate.
One other thing.. If your rear belt is really loose, perhaps check
and ensure you are running the correct pulley.
Also for new parts, the best support Ive found for TM parts is Peter at rcmanufactory.com, he's the most (no offense to Wolf Hobbies - Never dealt with US as postage costs are too high to Australia) knowledgable and when you submit your request for parts tell him what model you run and he'll adapt the order correctly.
