I have an 82 D150 two wheel drive, slant with 833 OD. The rear end is an open 8-1/4, about 3.55 gears. I'd like to add a sure-grip to this, but I can't seem to find out what will fit. I understand that some of these rears had 27 spline axles, and others had 29 splines. Does anyone know what splines I have so I don't have to take it apart to figure it out?

The next question is, would any 8-1/4 SG with the right spline count fit? I think I found one in a mid-to-late 90's Dakota but again, I can't seem to find solid info on this rear end either.
 
i think your 8 1/4 is 27 spline and the early dak is also. but later daks(6 bolt wheel ones i believe) were 29 spline.
 
I just checked dakota/Durango forum and I was incorrect. Pre 97 is 27 spline and post 97 is 29. All 9 1/4 were 31 spline. Hope this is what u r looking for.
 
Wait what?
You have a slanty that peg-legs with 3.55s? lol. I bet that 3.09 low gear has something to do with it. What size tires?

Haha, I don't know if it peg legs or not. I bought it as a dead dog and I'm 95% done getting it running but the last 5% is proving to be painfully stubborn. I want the SG for traction in lousy weather conditions, not for racing. Although I will take it to the track. Tires are very old 225/70/15, I will be replacing them with 235/70-15 when I get it on the road.

Many thanks, this is what I was looking for!
 
I’m not 100 percent, but I think the carrier bearings are a little larger on the truck version. Something to look into if you order parts

A SG , IMO, is a poor substitute for good tires.
On ice, or hard-packed snow, it can put you into the ditch in a heartbeat. Same when hydroplaning.
As soon as one tire looses grip back there, they both loose grip. And when that happens you only have milliseconds to correct before you are sideways, and on the way to spinning out. The best thing to do when you feel it, is to slam it into neutral, before lifting off the gas, and let the tires catch up; but you gotta be fast. Your hand has to already be on the shifter. That move has saved my bacon many dozens of times, perhaps hundreds of times in over 50 years of driving .
Other than for splitting the power on a dry paved surface,
about the only other thing a SG is good for is in mud/loose dirt, and for getting unstuck, if you end up in a snowbank.
However; With proper tires for the season, my 1980Volare, which I have had since 1994, I'm trying to remember if I ever got stuck with it...... but coming up empty............. hmmmmmmmm.
I think every car, or almost every car that I have had since about 1970, has had season specific tires all around, and most of the winter tires have been studded.

Oh yeah, I remember one time in the Volare. It was very cold out,like hi-30s below, and the third-winter studded winter tires were frozen hard. I wasn't stuck, but with just a lil snow in front of the front tires, she just couldn't get moving.
I remember now, calling in to work storm-stayed, and then later on, getting new tires,lol.
I can usually get at least two winters out of a set of rear winter tires, but after they go hard, (sometimes as early as the end of the first winter), and if they still have decent tread, I burn them off in summer. So some summers, my car might have summers on the front and winters on the rear. But if they were studded (usually are) I have extracted the studs for summer.
Oh yeah, I run oversize 15inch tires too,lol. 275/60s on the back in summers, and either 225/75s or 235/75s all around in winter. That stinking Volare, in second gear and humming along at 30/35mph , can bang thru miles and miles of bumper-deep drifts.
I have a SG for the 7.25, but have never installed it,lol.
