im thinking about doing this and wanted to know if it will work i was wanting to do a advanced adaptors sye and use a front ds will this work or do i have to get like a tom woods ds

 

You can get a front shaft shortened but the tubes on those aren't as thick as your factory rear. Tom Woods is top of the line, try looking for a local driveline shop, should be able to get one for around $150-200 and it will run you at least $50 to have the front shortened plus replacing all 3 u-joints, you come out better having one built.

 

ive known people to be able to just bolt the front in... no problem... theres several different lengths of driveshafts depending on engine... tranny... axle... and the amount of lift you have... just all depends... also ZJ's have been used... but are all different lengths also... lol... im sure theres a chart somewhere that will help you... but i gotta get to bed so cant do much else for ya tonight...

 

I HAVE the Advance Adapter's SYE.
-and-
I am using a "stock" front driveshaft.
I have a 3.5-4" lift.

I had to shim the rear (3*) so the pinion is pointed towards the TC.
I HAD a 1" TC drop. (Haven't gotten around to removing it)

The driveshaft is close to the end of its slide.

There are "stock" Jeep driveshafts that fit AND are a bit longer.
I believe there is at least ONE ZJ front driveshaft that would work. If memory serves me, it is something like 2-3" longer.

I went to the Napa website and did a parts search.
They show the center to center dimensions.

Not an EXACTING answer to your question, but it should be helpful in pointing you in the right direction.

 

I'm at 6.5" in the rear with a RE hack 'n' tap and a 93-95.5 v8 ZJ front shaft. Works great no bottoming out or over extension.

 

thanx for all the input i think im going to end up with the tom woods ds anyway just to save alot of hassle but if i could have i would have used the stock front ds

 

iron rock sells there hack-n-tap kit on ebay for like $200 for everything... including the driveshaft... best deal... and you dont have to break into the case... and people have now been wheeling with it for a few years and none have had any problems... S.Y.E's are over rated in my opinion anymore...
