Dang Ron68, my hats off to ya.  Just reading all that you've done was a little intimidating.

Further update: After much dragging of feet due to "other priorities" I have almost gotten it all back together.  Replaced almost all the bearings (can't do the one in the planetary as it seems to be built around it, but it feels really smooth). Installed the updated anti clunk spring after many calls to some transmission places who should be able to tell me if the updated (2004) spring can be used in a '98 gearbox or not. Many didn't know, but a couple said no problem, so I took their word and put it in. Now that it's in, can't see what all the fuss was about. Fits and functions fine.

Got the intermediate clutch built up, but had to make an extra trip to the transmission parts house for an oversized steel disc to meet the 1.634 to 1.636 measurement requirement. The total stack up measured right on for reusing the nominal sized plastic thrust washer.

Got the mod kits and got the OD servo piston modified, new style accumulator pistons and updated springs and am finishing up the valve body mods - just waiting on new solenoids to appear that I got on Ebay, and I can install the valve body. Got a shift selector shaft out of a 2002 Mustang, so I now have the correct style shift lever, also got the MLPS switch with it too, and the shifter assy, with the cable. It has the overdrive cutoff button on the shifter, so I don't have to install it separately. I just have to modify it to fit the '68.
Still need to get the US Shift Quick 1 controller, TPS for the Edelbrock carb, and the wire harness ($725 for all that!!) and the torque converter.

Got a little extra money last Wednesday with a bunch of overtime on a trip I made to Puerto Vallarta to replace an EEC (Electronic Engine Control) on a 737. Ended up changing both engine EEC's as the software versions weren't compatible. Man, was it HOT down there!! Road trips to other countries are a real goat rope. Customs, logistics, no parts availability, etc, etc. Still, we got it done and flew it home to Seattle. Now I feel better about getting the controller and stuff.

Got to talk to an expert about what torque converter to get - just going to do normal street driving with maybe an occasional run on the strip just to see what she'll do. I currently have a 2400 rpm stall converter on the C4, and it has worked just fine.

In a month or so, I will be putting the '68 out of commission to do the mod. I am really hoping to be able to use the Heddman long tube headers I have, but will have to see really how much room I will have with the 4R70W. I have read that the '68 has more room in the tunnel area than the 65-66 cars, so I hope that translates to more room between the header pipes. Don't really want to spring for a new set of shorty headers.... Well, that's it so far. We'll see in a couple of months if I put the box together right or not....
