How to tell what, trans/t case/axles my yj has??

Hello, I just purchased a 87 yj Wrangler and would like to know what it has in it. I know the 4.2 engine and trans arent original. I know the 87's came with the Peugeot ba10 five speed trans and a np207 t case. The front axle should be a semi floater dana 30, and the rear should be a dana 35. I read there is a factory option to have a rear dana 44. Also, a rear trac lock diff was offered on all models but the S models. How can I tell whats what? Also, Im trying to figure out if my wrangler is a base or if it has a package. Its faded and barely visible but on the hood it says wrangler along the sides, and theres 3 striped that wrap around the top part of the hood, along with the middle raised part having a solid decal over it. Thanks for your time guys let me know what you think

Its a quick video and it got fast forwarded while uploading however some of you may be able to determine whats what. I see theres a 30 stamped on the front pumpkin, Im guessing its a dana 30.
I can get another video once I clean it up and stick it on a lift. Started to rain so I only captured a quick video.

Thank you! One other question, thought id ask instead of creating a new thread. Currently have a 33s with a 3in body lift. Loaded down the rear wheels were rubbing on the fender flares. Im considering getting different flares but what about a 2in shackle lift? I was thinking about larger tires but for the time being Im keeping the 33/12.5/15's. Thanks a lot

2" shackles are not recommended.

You throw your steering angles way out of whack with that large of a shackle lift (when you lift one side like with a shackle lift, you rotate the axle, read up on alignments for why this is less than ideal).

Save up for a decent spring lift to where you can run 33's and lower that body lift as 3" body lifts are generally frowned upon as well due to the stress they put on the body mounts.

Recommended spring lifts are BDS, OME, and Rubicon Express.

Iv been reading that people have run into issues with that. I just sold my daily driver in order to put some new parts into the wrangler. Would I just buy a whole kit and remove my body lift? Im new to jeeps, let alone lifts. Would like to gain another inch or two atleast, over my 3in bl.

What "I" would do:

Piece together a 4" lift with some BDS springs/shocks (about 600 bucks), 1/2" Booms (50 bucks through ground pounder fab on the board here), brake relocation brackets, a drop pitman arm, t-case drop (until you can afford a SYE/rear drive shaft), and some shims as necessary for the rear pinion.

Then I'd cut down my 3" BL pucks to 1" and replace the bolts with shorter ones, ditch the track bars/sway bars, and call it a day. There are cheaper ways to do things, but this is what I would do. It is made of solid parts that are gonna work well and hold up. It also gives you room to expand later to 35's if you want.

I'd also start saving for a rear axle swap if you plan to increase tire size and/or lock the axles in the future.
