Can this be done w/o a doubler? I don't want to lengthen my wheelbase to fit a doubler, but I do want to tuck my front drive shaft up higher...I have the oval pattern 205....

Contact WMS and see if they'll do it. The worst they can say is no.

Been wondering about that myself. I have the chevy style figure 8 bolt pattern in my TJ and I would really like to get that front output up about 3 inches so it's level with the bottom of my sm465. One other advantage would be dropping the whole combo an inch and get a better driveshaft angle on the rear, right now my rear output sits about an inch from the floor and my front output is about 8 inches from the floor.

Dave (Might just make my own indexing adapter this winter when I tear it apart for some minor adjustments;)

Yes!

Alright, now how about some info....

sorry, don't have any. But if you do a search from about a year ago thats how i got these pics. Type in 205 index and see what you get. Good luck.

Yea, I guess I responded to that post also. Seems everyone is running D300's and Atlas T-cases. One more trip in Sept. then I'm down for the rest of the year so I'll take mine out and see what can be done.

couldn't find the post, but how bout this for an idear...

take a 700r4 output shaft and put it in a th350...are they not just a longer??? same spline count, etc??? Then, I could bulid a clocking plate (if the difference is at least 3/4") to place between the two, but still maintaining full spline engagement. Even if the splines are not long enough, getting them cut would only be like 50 bucks....fire away....!

Even better idear...call foothill offroad in SC and have them send you the right adaptor for clocking the hourglass 205!

Not sure this is of great help......but on my Ford we just took the adapter...looked at it alot......measured. Took sum plate to a pal with a water cutter and he built what we needed and we made our own adapter outta steel. (tossed the cast one away) I went to get some pics of it but ya can't see a thing in photos ;-(
But I imagine you can get the basic idea. I will be doing it again here in a month or so when I toss a Chevy 205 on the back of the C-6 soon as I figure out the oddities of all thats involved in that swap.

AlumCJ I answered your post on 2track BTW.

any body got a phone ## for foothill offroad ??? thanks 55guy

Try posting this in the Cruiser section, there was a dude there last year that was making and selling them. I'm thinkin RockCruiser Ryan was close to his user name, something to that effect anyways. :skull:

I ran across this thread while searching for "WMS" measurements for SRW 85ish GM pickups (D60 & 14B)...

BUT, since I'm here I was wondering...


Brawler, do you have any oiling issues with your NP205? I wish I would have found this pic a long time ago, it would have helped speed up my decision making process. Here's mine.

I was worried about doing it because of possible oiling issues.

it's MUCH easier than you may think.
i've done it in the "frog" and it works just great.

take the adapter(whatever adapter you have, it does'nt matter), and cut it in the middle, side to side.
then, reweld it exactly as you want it to be, meaning clock
it to the point you want the t-case to stand, and THAT'S ALL!!

two point to be aware of -
one, be prepared to use a CV or other means to compensate
for the new angle of the front driveshaft. you would'nt want it
to bind and blow.
and two - it would be wise to relocate the oil filler so you wo'nt
have a problem filling enough oil.

thththat's all folks....:) :)

Great idea Frog, pretty simple.

-Why would there be oiling issues? I don't understand. The oil level would be higher than normal since the fill hole would be higher. :confused: I wouldn't be worried about it.

Look at the pic, the fill hole is a little higher, but there is MUCH less space for the oil below it. Also, with the lower shaft assembly located higher, and the oil fill level not reaching up as high on the assembly, it could cause some problems. Not knowing the 205 in detail, and being too lazy to look it up, I don't know that there would be a problem, just making and observation on your comment...

To help with the oiling issues just fill it to capacity through the vent.;)

I just welded a 1/4" NPT bung about halfway up on the inspection cover, ala ORD, and use that for a fill.

the 205 can be clocked with a Klune;)

How much floor did you guys need to cut out to clock those 205's?

Its a circular pattern. Y not just re drill & tap the input side of the NP205?? Put the adapter on the case, clock it accordingly, mark the holes, start drill/tappin. The adapter is hub centric so it will center itself. Just make sure the bolts don't stick through to far if yur using fresh ones :flipoff2:
Beats the sh!t outa welding the cast adapter IMO.

none.

the adapter is a 6 holes one, so you cannot just move it by one
hole. one hole = 60 degrees and since the original t-case
position is 45 degrees, one hole means 60-45=15 degrees, i.e.floor cutting.
if you do it my way(see above), you can clock the two halfs
as much as you need/want, preferably horizontal, and then
reweld then.

don't think so.

not enough "flesh" to drill new one.

besides, drilling additional holes will definitely weaken
the adapter. the 205 is one heavy m.f......:eek:
