i have a 1979 luv 4 speed manual and have found a 1985 isuzu pup with a 4 speed manual with working engine just trying to figure out if the trans and engine from the pup will fit right up with my truck any knowledge on this subject would be really helpful

Sorry, I'm ignorant on LUVs, but I know a little about P'ups. Does your LUV have a hydraulic clutch, or cable? That's the only potential issue I can think of right now.

both truck are cable clutches really the only thing i am worred about is if the length of the trans is different on the 85 pup then my luv

The '85 should have a 1.9L G200Z engine, which is just a larger displacement version of the stock Luv engine, it fits, I have one in mine. The difference is it may have a mechanical fuel pump instead of the electric on the LUV- either one will work fine.
The tranny is the same size. Make sure the output shaft is the same size & spline as the LUV, if not use the splined yoke from the '85.

thank you so much for the much needed info on this subject i really appreciate it

79/85 its the same MSG trans as far as gearing, case size and spline count.
86/87 is the hard to find 14.5% O\D trans, same MSG trans with a 5th gear (case is 5" longer) and small change to 1st, 2nd, 3rd gearing.
all MSGs 79/87 are the same low range gearing.



only possible changes 79/85 i know of are......
the front bearing retainer on 4WD 4speeds.........some are 4 bolt some are 6 bolt.
where as all 5speeds 2 or 4wd are 6 bolt
and the oil fill plug on a 5sp 4wd is a 1/2" higher.


the diesel housing has the starter on the op-pest side of the gasser, thus making a housing swap needed if you had a diesel.
but thats not a issue for you, since you don't have any need to swap housings.

"you have a gasser"
