Here is a Web site that will help with what a '83 CJ7 would have come equipped with:
Short Jeeps: CJ-7
As LT1CJ7 stated, a '83 would not have a V8 ('81 was the last year) and the tranny would be a 4 or 5 speed, transfer case should be a Dana 300.
The easiest way to post pictures is to open a free photobucket.com account, download your pics, (keep the pictures at of below 500 KB for proper size), copy and past the .img file into your post.
It would help if you could post some pictures of the drive train components. The forum will be able to identify exactly what you have.
Welcome to the Jeep Forum and Congrats on the new CJ!!
Hope this helps.........
