you want the 83 L52 tranny, the other one was junk
it's a direct bolt in for the most part. you'll have to grind down the splines on the t-case, since instead of having a relief area on later cases, the 4 speeds had raised splines past where they really matter
if you get a later tranny, you'll have to get new driveshafts made(or find a suitable donor), and relocate your t-case crossmember.
100,000 miles im having trouble keeping the 4 speed in it for 5,000 miles you eather baby the livin hell out of it or your rilly lucky

I have a 1980 4wd with L43. I am installing a L52 and would prefer to use the transfer case out of my 80 as I know its condition. The spline on the 80 does not taper like the 83 does. Do I need to do anything to those splines on the 80 transfer case? If so can I just pull the input gear out of the 83 case and install in the 80 case? Thank you in advance! Michael
To install a L52 in place of a L43 you must change...........Fork, release bearing and collar, slave cylinder with push rod, two lower bellhousing bolts, trans handle, trim floor for top shifting handle instead of side shifter.The crossmember, drivelines, starter, flywheel, pressure plate and clutch disk will all work just fine.Marlin
what is the best method for ginding down the splines and approx how much needs to come off. fixing to have to do this.
I haven't yet found a need for the elusive 5th gear ever in my truck but I'm old and drive/live slower than a lot of folks
