The block and heads are identical on the GTO SWB and LM. The LM had 6 carbs like TR and GTO. SWB comps and SEFACs had 3 carbs. The LM and 275 and 330 Ps were the last cars to use the columbo 12 i can provide lots more details if needed. You could probably use gearbox from gt40 or P4. HRM has detail kit for P4 that'd help, add 250 motor or rmcm 12 too. I've done an academy LM and a Drogo nosed car to represent the 65 lm winner. Academy body is a short nose car. Actually prettier than Drogo nose imo. Good luck.
Multiple. One stalls, I switch to another, and new stuff arrives that needs fiddling and appraisal before entering the "abyss of projects future". Parts assessment more important now that Don and Carol headed to retirement. Not wise to make a list to order later. Bummer. :^(
Tim, thanks for update. I've got a bunch of these, original issue great. http://www.bonediggers.com/1-2/deora/deora3.html Bonedigger's site has nice article about the car, kit, and a few things that varied. The taillight panel did not have external lense, it used reflection from above IIRC. A few other minor things too, and fun trivia about the car. Glad I get more clear covers out of this. I buy builders with the bubbles/tonneau. Original mags were small, kind of Halibrandy. Tires had add on plastic sidewalls for width, Firestone markings. Wheelwells narrow, so need to rout out if you want bigger tires.
One piece like low riders iirc. Look great. Width on the money. Have been in last few issues, 510 too I wish the 510 with stock seats came back. I think stock door panels on back side of race door panels, clever for '70's.
The GTO they recently did was the GS iirc. GS did a SWB too. Here's hoping for the Italeri. Much better. Esci is trash. Very abnormal for Esci, their other stuff is pretty nice, big thread about them somewhere here.
