Except for the main chassis, my brother and I built about everything on out RED's.
They are shorty's though, so nothing fits like the big guys use.
(180" wheelbase)
Also run Pontiacs so not much fits from other suppliers either.
(like Glenn's engine)
Built all the steering linkages, throttle setups, shifters, engine mounts/brackets/plates,rear end mounts, brake systems, dashes, etc.
