    Finished up replacing all 8 spring brackets and straightening out the rear crossmember to a useable fashion.

    Spent to much time cleaning up the D-44 flanged rear diff. Used both 5/16 and a 1/2 NC tap to clean up threaded holes and a 2 1/4" bottle brush hone to clean the inside of the tubes.

    All the parts were worn but not abused. Will need to replace all bearings and seals and change out the R&P to 5.38. Will install a new NOS clutch pak in the Power Lok. Once together, I will install Metcalf's disc brake conversion for a D-44 flanged which will include an electric E-brake system.

    Finally found a Power Lock series 4 for the D-30. The buyer mentioned that it had a broken left hand thread grade 8 bolt that needed removal.
    Since I don't have left handed anything I took the part to two machine shops and neither were comfortable with doing the job. This sucks! However, one told me to get a hold of a guy that does "SINK EDM" say what? The machine shop owner showed me the process and I was blown away at how it all works. Very high tec. It's darn expensive but he referred me to a guy that's fair priced. Mailed it out and got it back within a week and the only way I know what hole was worked on was due to being marked by the machinist. He never even had to retap the hole. I am impressed!
    His price was way fair.

    Here's a link that shows the process......

    We used EDM a lot at United Airlines in the engine shop. Often made the difference of being able to repair a really expensive aircraft part or scrapping it.

    the pic below is showing what most of us would recognize as half of a case of a series 3, D-44 power lok. Is it? I'm unable to match any of the numbers up with dana spicer P/L units. It appears to be a aftermarket unit and I'm unable to find one darn thing about it. anyone have input? This came out of a '71 d-44 flanged off set diff.
