Front drive shaft
I can't seem to find much information on front driveshafts. So here goes. What is the difference between a 1983 and 1984 or 1985 drive shaft? Are they the same length or close? What about the ifs shafts? They are shorter with less slip. Right? The reason I am asking is I am watching a driveshaft on ebay from an 83 that could use for a core for my sas.

I think the 83 is the same as 84-85. If you're going to sas you wont be able to use any stock driveshaft it will just be too short.
You could make a square one for super cheap like i did. They have tons of travel and are super strong.
Or you could go about 300-500 and order a custom long spline

I don't know that much about it, but wouldn't it be cheaper to get a driveshaft and have it lengthened then have a new one built (Assuming that I didn't want to go the square tube route). On the other hand, just out of curiosity, what size tube did you use? Is that just 2.5x2.5 with .25 wall with a 2x2 inside?. Where did you get the u-joints?. How fast can you go with you 4x4 engaged before you notice the drive shaft wobbling? Sorry for all the questions, but I have considered this option too, I just really like the idea of having my drive shaft ballanced so when I drive through the snow I don't have to unlock my hubs all the time.

I believe they'll balance it and all to so if it's a DD or you're locked in on road, then you'll want to have a decent balanced shaft.
I had Jesse at high angle build both of mine. Very happy with the results; although for having $800 wrapped up in both of my shafts I guess I'd better be pleased!

One more question. Does anybody know if the bolt pattern on the pinion flange on an IFS diff is the same as the bolt pattern on the pinion flange of an 8 inch.

I know the drive shaft shops can lenghten and balance your STOCK driveshaft for around $100 or less. Custom 10" long spline balanced shafts with super u-joints are gonna hurt your wallet. Tom woods makes a nice shaft. As far as the bolt pattern goes They should be the same 79-83 had a differnet pattern. No big deal though if different you could swap pinion flanges or drill the new bolt pattern in the flange

If we got much snow here i would have a different driveshaft cause i know what its like to have to drive 45 on the freeway in 4wd and that would suck with a square DS.
If i were you i would just lengthen a stock one unless you have the money to buy a beefier long spline.
