I would like to know if any1 out there has ever done this?

Is there any 3rd members that will fit the 85 rear large axle housing that will give me a better gear ratio like 4.30 gears or up that I can just bolt in and use my large axle 26 spline?

I will be going junk yard shopping and don't have much money at the moment.

Trying to way my options and the cheapest.

So I really don't wanna waste my time with parts that will not work.

I wanna go there and get what I need without having to change the ring and pinon gear. I don't have the tools for proper set up here. I need plug n play.

I am trying to find a chunk that can just bolt in with what I have and let me be on my merry way riding again.

Is there a way?
What I would like to know if there is a way to do this?

Read this:

1600, 1800, 616, 618, RX-2, RX-3SP, SA & FB RX-7, RWD 626 and '86-up Mazda "B" series pickup truck third members (also aka pig or pumpkin) are interchangable. 1984-up models use larger axles, so the side gears in the differential are correspondingly larger-splined and must be swapped for correct gears if substituting into an earlier housing with smaller axles. Pre-SP RX-3s can use the later third members if an SP driveshaft is substituted along with it. Some pickups had 4.44 ratio gears, but never in conjunction with limited slip. The Mazda part number for the 4.44 pickup ring & pinion gearset is M054-27-110A. As the chart shows, '94-up Miata gearsets are also interchangable. See Randy Stocker's Miata Drivetrain Interchange page for more information. See Driveshafts for related differential flange issues. See Rear Axles for additional related issues.
