fyi, the red truck of marlin(if it is his') is an RN46...if i am correct...
the R means it has an R-model engine like the 20R or 22R and other numerically lower numbered engine released by toyota.
um NO, Marlins truck is a RN 38 -1980
my 1979 is a RN37, my truck originally had a 20R with L43 4speed and 4.37's
