Don, I'm also planning on doing one more modification to Ted's K member. Now that I have enlarged the bolt holes, I will be welding on 4 shaft collars 1/2" ID and 1" OD. to the bolt holes.
After everything is "Nice & Straight" I'll be removing the four bolts, one at at a time. Then replacing the bolt with the correct length (Perhaps bolts custom cut to length, so only unthreaded portions are exposed to the collar) with a shaft collar and then welding the collar in place. This will act as a perfect dowel fit locating system. You can now pull the IFS and replace it and know you are aligned.
The shaft collar will have a 1/4" UNF 28tpi thread with a binding screw. This screw will also act as a locking screw to the 1/2" diameter bolts. Thus reducing your reliance on just the spring (star) washer.
If you go this collar route you do not need the 1/4" x 3/4" key stock welded in as locator blocks. I did this method first and may even remove them later.
I wish I had saved all my email's to Ted. I was giving him a blow by blow description. Would help me too as a good reference.
BTW, If your IRS bushings (needle roller bearings) need attention, you may want to look into the solid Nylon style bushings that are offered my a number of outfits.
Good luck with the work,
Arthur
