#1.  I've been told that the front ring gear diameter for the 1991 2-Door 5-speed Sidekick is 6.9".  Is that correct??

#2.  Does anyone know what the rear ring gear diameter for the 1991 2-Door 5-speed Sidekick is??

Why do you need to know the diameter? What are you trying to do?

#1. Aren't spacers required to use Sidekick R & P Gears in a Samurai??

#2. What's your reaction to the statement at the following website that says that Yukon Ring & Pinion gears will fit the Samurai or Sidekick/Tracker vehicles??

http://www.roadlessgear.com/page/RGL/PROD/D/YGA100

Only front trackick gears will fit in samurai axle housings.  The rear trackick ring gears are too big to fit.

A can (to hold the crosspins from sliding out of the carrier, since the trackick ring gears are tapered on the inside) and a shim (to compensate for the ring gear thickness and the ring gear mounting position on the carrier) is needed to use trackick gears in samurai thirds/axles.

Trackick front, and both samurai front and rear gears will all interchange.  So if you need gears for the rear of a trackick, they will need to be bigger.  That website is kinda misleading on the way they have it worded.  And I see no place to specify if you are ordering gears for a trackick or samurai.

Those gears will fit in the front of a trackick but not the rear.  I would hope they would tell you that when
you order them.

Any your point is?
Maybe you need to tell us specifically what you are trying/wanting to do......then we can give you specific answers to your questions.

#1.  The following webpage gives detailed information on the Samurai R & P:

http://www.precisiongear.com/suzukiring.htm

#2. Does anyone know of a similar webpage for the Sidekick R & P??

 If you are trying to regear your Track/Kick, why are you only going to 5.29s? It already has 5.125s. What size tire are you running or trying to regear for? Calmini has 5.83s available for the front and rear of Track/Kicks.

As the following webpage shows, the Calmini R & P Gears for Sidekicks/Trackers have been "Temporarily Discontinued", & also, the following webpage also shows that R & P gears were NOT offered for the 10 Bolt '89-'92 Rear:

http://www.puresuzuki.com/Ring%20&%20Pinion.htm

There's a good recently revised thread at the following URL on 89-98 Trackick R & P gear ratios that's based on year, body style, engine, & tranny combo, & that also gives the following tooth count:

4.30 gears have a 10/43 tooth count
4.625 gears have an 8/37 tooth count
4.875 gears have an 8/39 tooth count
5.125 gears have an 8/41 tooth count
5.375 gears have an 8/43 tooth count
5.625 gears have an 8/45 tooth count
5.833 gears have a 6/35 tooth count (Calmini)

Because of "Topic Merge", the CORRECT URL should be:

#1.  The following URL says that the stock transfer case gear ratio is 1.409 in high range, but I thought that every transfer case gear ratio was always 1.0 in high range!!  What transfer case are they referring to??

http://www.izook.com/tech/math/gearing/gearingtables.htm

#2.  I thought that the stock transfer case gear ratio for a 1991 2-Door 5-speed Sidekick was 1.0 in high range, & 1.85 in low range.  Am I wrong??

#3.  Are these the correct tranny gear ratios for a 1991 2-Door 5-speed Sidekick??

1st 3.65
2nd 1.95
3rd 1.38
4th 1.00
5th 0.86
Reverse 3.67

According to the following thread, the GV and XL7 front R & P gears fit Samurai carriers without the need of cans and spacers:

REPLY from "Whitfield":

Actually the design of the post was to get a Steel 5.125:1 geared housing into a Kick or Sammy. The Complete GV steel front unit will change into either a Samurai axle or a Tracker front axle. NOT that the Gear Dia or thickness would be a direct swap into a Steel Sammy carrier. I would bet the GV ring gear would still need the can and spacer.

According to the following thread, the correct tranny gear ratios for a 1990 5-speed Sidekick are the following, & wouldn't the tranny gear ratios be the same for any 1989-1998 5-speed Sidekick/Tracker??:

Gear ratios 
1st 3.65
2nd 1.95
3rd 1.38
4th 1.00
5th 0.86
Reverse 3.67

the tracker front thirds will bolt directly in place of the sami unit but people have had issues with the aluminum section cracking. the gear carrier in the tracker unit is not as strong either. the best route for one to go would be to put tracker front gears in the samurai third members and to use the can/shim kit with them. this is providing that the gears are used units and not new replacement gears.
