Actually there were quite a few 4 barrel equipped 440 Road Runner/GTXs produced in '72-'74- the '72 4 barrel was even available with a 4 speed and Dana 60 driveline. The 4 barrel 440 cars all seem to have had small GTX emblems in addition to the regular Road Runner trim
There were a handful of 440 six barrel cars produced- very early in the model year as this engine was cancelled- two Chargers and one Road Runner
still exist- the Road Runner not having GTX emblems. The 6 barrel was available with an auto trans only soall had the 8 3/4 rear
There are also versions available with no vinyl top- the earlier (but still readily available) Dick Landy '68 kit features the '69 side marker reflectors and no vinyl top
Would hate to guess a specific caster from am ebay pic- basically a copy of the the MPC 75 Laguna (also released in the "Cannonball Run" series as the Hawaiian Tropic car)
Correct chassis and interior for a curbside are already there in the Revell '77 Monte
The NASCAR rear wheelwells look like they could be used as a basis for stock front openings
The full size wagons were even bigger- the Ford products were wide enough they made the "third row" seats face each other rather than backwards
Ford called their tailgate design the "Magic Doorgate" - not quite as trick as the 71-76 GMs which had the clamshell with the halves that disappeared into the roof and floor
Is the tail treatment the same as the "custom" parts from the earlier annuals? I got some incomplete buildups including a 67 and 68 annuals- one had been built custom with the "GT" rear panel
But before '70 the manufacturer had to also sell the same size engine hence the street Chevy 302 and Ford Cleveland 302s
The 70 rule change allowed the destroked engines for racing- most dramatic difference was probably the Pontiac Firebird- race cars ran 303 cubes- the street version 455
Staying with the kit engine on this one- added the crude power steering pump from an AMT Challenger and a few homemade detail bits
Mockup with a coat of color
Also did a "test shot" on regular paper of the green stripes
Get the AMT Road Runner GTX as a chassis donor if you want bucket seats, the '68 Road Runner if you want a bench seat- the GTX also comes with a 440 engine and your choice of 4 or 6 barrel carburetion if you don't want to build a Hemi
Kept it simple on the chassis- am keeping it close to out of the box to keep the "vintage MPC feel"
Another mockup with the wheels and tires painted and an intitial coat of primer, still some bodywork to do
