Helping a Friend need a Dificult part
 

Greetings everyone, i got a friend that is looking for a full floor or the part where the back seat begins with the bases of the braces and the trunk floor of a RX3 or 808. is to restore a Rx3 1973 that was cut to 3/4 chassis car and he wants to rescue the car and restorted to is original flooring. any help or advice on what he should do to restored the car back to factory condition will be appreciated.:nod::nod::nod:

I don't normally venture into this section too often, but parts are my speciality :) Just to make sure, is the car in question a coupe, sedan or wagon?

From my understanding of the RX-3 parts catalog, the main rear floor section (Location #14) is separate from the bulkhead under the rear seat (location #24). Then there are the rear wheel arches (#18 & #19), reinforcements (#20 & 21), trunk floor edges (#22 & 23) and a funky little hump-shaped bit at the tail of the car (#29). Anyway, here are the part numbers for each of the above parts for the Coupe & Sedan versions:

#14- Pan, Rear Floor: 0866-56-210C (0866-56-200C for after March 1973 builds)
#18- Panel (R), Wheel House: 0866-56-330
#19- Panel (L), Wheel House: 0866-56-830
#20- Bracket (R), Damper: 0866-56-350
#21- Bracket (L), Damper: 0866-56-850
#22: Panel (R), Floor Side: 0866-56-381 (Sedan)*, 0378-56-381 (Coupe)*
#23: Panel (L), Floor Side: 0866-56-881 (Sedan)*, 0378-56-881 (Coupe)*
#24: Member #3, Cross- 0866-56-400
#25: Member #4 (R), Cross: 0866-56-450A
#26: Member #4 (L), Cross: 0866-56-470A
#27: Pan, Spare Tire: 0866-56-481A
#29- Insulator #2: 0866-56-702
*Add an "A" suffix for builds after June 1973

As for the Wagon, it's much simpler so here's those too:
#4- Floor, Rear: 0899-56-300E
#5- Member (R), Rear: 0585-56-330B
#6- Member (L), Rear: 0585-56-830D
#17- Support, Seat: 0187-56-235 (2x required)
#29- Cover, Service Hole: 0585-56-901A
#30- Tape (AKA Seal for Service Hole): 0585-56-902

As for tracking them down in new, fresh form, Ray Crowe at Malloy Mazda would be my first call. Beyond that, you might ask Aaron Cake or maybe Logan at Defined Autoworks (GTORX7.)
