N/A FC Final Drive Gear Idea

[Whizbang]

So after much searching and looking into parts compatibilities, i have found no known supplier of gearing for the NA FC aside from the 4.3 (which was OEM anyway).

BUT i came across another idea. If this works....oh man.

The FC differential is, as you know, an IRS setup. BUT it still uses a front loader style differential. For what ever reason an FB front loader can attach to the FC housing. There are two extra bolts on the FB housings, but generally, it lines up well.

The FB as you know, is the longer pinion design and has a varying ring and pinion options.

Now this DOES present a problem. There is no front diff mount location on the FB component. Screwed? Not yet. The mount is pretty simple. Either some welding could work OR

Enter the Kia sportage front differential. As i have written about before, this is compatible with the 84-85 FB. But has a large extension with a hole from suspension piece on the kia. (see below)



Its also on the same side as the FC mount, so my plan is too then weld an adapter piece that mounts to the Kia diff and the FC differential mount (at least the location the mount itself attaches to the sub frame).

The axle stubs of the FC should with whatever LSD i put into it. Drive shaft might have to be lengthened. I am going to try and cobble this together soon enough. I just need the parts to get things working.
