XJ shaft conversion question

I have my big joint XJ axle shafts in had, ready to install.
I need to get the seals, and am going to fabricate a vac. housing cover.
Does anybody have the dimensions of the housing?
Is there a gasket available that I can use as a template?
Thanks!
Also, can anybody verify that a National seal # 710068 will work for the seal on my passenger side carrier?

I pulled mine off, pulled the fork out and layed it flat on a piece of scrap, traced it out and cut it.

I just made a cardboard template using the vacuum actuator.

I just took the fork off and reused the original housing as a block off.

That's a good idea too.
I have a Posi-Lok, though, and I'm going to sell it when I swap.

I am curious. By doing this will this not make it so that your front driveline will spin while driving, causing vibrations since the front driveline is not balanced. Also won't this cause some issues for the transfer case as well?

I know that around 55-60 when I have my hubs engaged it does this on my jeep and it can't be good on the t-case. - I don't do this often or on a regular basis either.

Mine does 70mph with the solid axle configuration and no noticeable vibrations.
However, I did stretch a front drive shaft from an XJ to replace my stock front YJ shaft.

I think the XJ shaft is balanced as they run this very setup already. I am just curious, I had entertained this same idea then opted for D44's and SOA instead.

Yeah, that's why I went with it, since the XJ's already did. Although clearance was close. I self-cleared my front exhaust pipe and the new drive shaft. Happened at full stuff.

When I had my front driveshaft rebuilt last winter, I had them balance it because I was planning on this.

u dont have to take the fork out. just take the collar off and toss it. the xj shaft isnt big enough to touch the fork with no collar there. mines been like that for yrs now no issues. and yes, u need to have the front shaft balanced or it will cause vibes.
