It's a 1980 so it's a part time 205 transfer case. I'd venture to guess that the cast iron transfer case is stronger than the driveshaft tube. It more or less only gets engaged in 4WD on the street to lube the front axle. It clanked and rattled and made funny noises before rolling down the street in 2WD with the hubs locked so I would say this is an improvement.I'd be hesitant to run that. If it were mine I'd rather have not enough engagement than not enough travel.
If you bottom out the driveshaft only place for it to go is to shove it into the tcase or diff.
Is it full time 4wd? If not then I wouldn't really worry about not enough engagement, and just take it easy in 4wd. Until you can get the driveshaft lengthened or the spacer machined down.
Not trying to fear monger or say you're stupid, I just don't want to see you blow out the tcase or diff!
I ran my stock length front shaft on my 4 inch lift for about 7 years 50,000 miles, splines just barely stuck out of the slip tube. Non full time 4wd. Finally had to rebuild the splines and had it lengthened I think 1.5 inches.
I follow your concerns and am somewhat with you but I will know more tomorrow on the bumpy street leading to the gas station. In 2WD or 4WD the front suspension will move up or down as needed. I drove it home 10 ish miles today but not on a long stretch of bumpy road.
(SW Houston- West Bellfort between Kirkwood and Dairy Ashford for those who know the area. Actually, Kirkwood south of Bissonnet to West Belfort ain't all that great, either.)
