caster s10b parts were purchased of ebay for backup spares for my d4,but don't have the need for them.i did build what i could to see what was missing.to build it up,you will need
- suspension arms
- front shock tower
- front top gearbox
- front suspension arm holder
- arm pins.
these are what i can remember but there is more if you dont have spares e.g shocks,turnbuckles etc.
reasonable price £25 ono posted.
