Changed Diff in my SDC today

So today I swapped the differential in my SDC from 2.24 to 2.47. The difference is not huge between the 2 but it really makes a difference on takeoff and cruising just below 60. With the 2.24 60MPH corresponded with 1900 rpm, with the 2.47 rpm climbs to about 2100. That 200 rpm change makes a big difference, and lets me shift at better times. To soon to determine how big an effect this will have on the economy. Here are some SDC pics with my R9 ronals, and BBS style weaves,

The Red wire is for the glow plug main power bus, the green wires are unconnected (remanants from the 300 SD wiring)
I havent gotten around to cleaning up all the wiring yet, but it will come very soon.

Yeah I need to adjust the valves and change the gasket soon.

There are some thread started by me, but I dont have the links, there are some results threads where I talk about getting 36 MPG with the 617 engine.
Ive posted about the trans swap as well but it isnt all in 1 concise location.
