Are these 3.5 or 3.54 gears?

I'm verifying with the PO I bought this from but he originally stated low mileage 3.5. I didn't realize there is a 3.50 ring and pinion, but apparently they are higher strength.

Ashcroft sells 3.50 as one source. This is from their website:

I want to fit the Heavy Duty 3.5 ratio ring and pinion in the rear axle but leave the 3.54 in the front, will this be OK ?
There will be a ratio difference but it is quite small, with the centre diff locked on a low traction surface this will be OK as occasionally one wheel may slip to stop the driveline 'winding up'. When on road with the centre diff unlocked, the centre diff will turn slowly to allow for the ratio difference, this slow turning will not wear the diff excessively. The only instance where this ratio difference could cause a problem would be if you were on the road or on a high traction surface with the centre diff locked which of course you should not be.

one small disclaimer on the this 3rd member is that the little brass female threaded cap that fits on the male brass fitting that the airline goes through is missing. easy and cheap enough to replace but no need for surprises.

Most would find it self explanatory that these are 3.54:1 gears.

Even if they were the 3.5:1 gears Ashcroft sells there would be no reason not to use them with the 3.54:1 gear sets.

It's not self explanatory. 3.5 is 3.5 and 3.54 is 3.54. If they were both of the same quality I would agree with you that the difference is negligible. But one would in my opinion increase the value while the other would not.
