Going back to the lexan/plexiglas rear hatch issue...
I just read in the article "The do-it-yourself Porsche" that a plexiglas hatch was delivered with the kit. This also matches with some of the period pics of a hatch delivered with the parts collection and Holbert offering a plastic hatch for about $400.
Who knows how accurate these old articles are. I don't find a listing for a plastic hatch in the available parts resources but I also don't have a gold standard reference. |

I have owned Tom Brennan's "instant legend" car built at Road Atlanta at the runoffs in 1980. In 1981 he won the runoffs outright and the car is one of 4 Porsche racecars on a factory poster for 1981. The car was also featured on the front page of Pano in Dec 1981.
The cars all had lexan hatches and the suspension was trick trick trick.
I also own a Frankenstein 933 variant. The car is all tube frame in 944 widebody trim. The car started life as one of the AJ USA 933s. At some point the car was totaled at Watkins Glen and rebuilt into a total tube frame chassis. The only part of the car that is original is the firewall to just behing the drivers seat.
The Tom Brennan #54 was in all 944 trim when I purchased it back in 1994.
More recently it has undergone a complete chassis restoration back to it 924DP days. Mechanicals are going back in now. I plan to take the car to Rennsport Reunion at Laguna Seca this fall.

I have the 1981 SCCA specs for the 924, its only one page, if anyone wants a copy let me know. It doesn't tell what was really used as many modifications are allowed by the 1891 GCR. If you want the entire downloadable package look at the RMVR vintage racing website under the rules subtitle. Among other things, using the 931 head is not really legal as the 933 head had its own PN, I had to get DMeluzio's verification and pictures that they were used to our Porsche qualification person for permission to use it.

The 933s cars came with mechanical injection which was junk. THis pretty quickly was removed and they went with the 931 head with webers. This turned out to be a much better arrangement. My car was raced extensively in the 90s in SCCA GT3 with the 931 head and webers.

This is a good question, and one for which I don't recall ever seeing a definitive answer. If I had to hazard a guess, I doubt that the factory would have provided a lexan hatch...it didn't do so on any of the other 924 special variants, as far as I know, so why would it have done so with the DProd? Any pix depicting a lexan hatch were probably team/owner changes. But I'm just speculating on that.
I've had a look thru my entire collection of historic DProd pix, and virtually none of the early original DProd examples show any clear evidence of Lexan. A lexan hatch almost for sure requires internal bracing to keep it from flexing and breaking (especially on the track). The only one that shows a lexan hatch for sure are pix of Frank Celenza's yellow DProd...but those pix are all after it was converted to GT3 trim. So if I were a betting man, I'd bet no factory lexan.
On a related note, I've been trying to determine whether or not the factory cars came with full-blown US bumpers with bumperettes, or if they came from the factory with fiberglass molds. I've looked thru dozens of pix, and in some, it looks like normal factory metal bumpers with bumperettes, in some it looks like fiberglass bumper with bumperettes, and in others, it looks like fiberglass bumper with no bumperettes. Again, I think it likely that the fiberglass bumpers were swapped on by the teams/owners.
And that leads to another question: if fiberglass was allowed, why did they bother making a mold of the US bumper with it's uglier "fat lip" profile and bumper pads? Why not just make a race version of the smaller, sleeker Euro bumper???
This is a factory-provided photo used to promote the DProd program. Looks like glass hatch and production-spec bumpers to me.

The Front and Rear Bumpers were molded fiberglass. The "bumperettes" were molded in and painted Black to look like a Std Bumper. I have a few of these in my DP parts inventory
