T-case drop still needed?

Looking to install a 1” Daystar BL and 1” MML on my 1993 YJ. Currently running 2.5” Rubicon Express suspension, 1.25”Boomerang shackles, 31” BFG ATs. When suspension was lifted a t-case drop was installed.
My question is, will the t-case drop still be required after the MML is installed? I’m not experiencing drive line vibrations at this time. Just trying to figure if the MML will cancel the T-Case drop and vise versa.
Hopefully someone out there is running something similar and can provide clarification. Searching the forum and web has just lead to more confusion and off topic ramblings, lol I will eventually be upgrading the rear to a Dana 44 and SYE, but later down the road.

The reading I did on Stu Olsons site says the MML will not suffice in place of the T case drop with a 2.5. I have a 91 with a RE 2.5 kit and tried removing the T case drop to see how it was and its a no go. Time for a SYE is I want the drop gone.

Thank you for the input, I’m with you, I want the drop gone as well, seems counterproductive to lift the Jeep then lower the guts.
 
I had that setup for a while.
2½" lift, with the 1" mm lift, and 4° rear shims, it required a ¾" T-case drop to get the drive line angles right.
I don't know what shims you have, so results may vary.

I’m gonna leave it in place for now and step up on ordering a SYE and 2 Low kit.

I’m running whatever ever shims came with the RE lift, I was reading your post from when you installed your TT, you went to 8 degree shims to adjust for the TT height change and angle, correct?

If it helps, my RC 2.5 kit needed 6° shims with NO tuck (for an SYE driveshaft). I would think 8° with tuck would be about right. But, this also all varies due to what engine and transmission you have. The autos and 4 cyls are shorter drivetrains. 4.0 manual ends up with a pretty short driveshaft which makes the angle changes more drastic when lifting. So there is no real one size fits all answer sadly.
