That shaft is 1.125” OD and tapers to .975 where the u-joint is. The steering wheel end is larger and 1.125”OD as well. It is a Gemmer box and worm and roller, too. A quick measure of the OD should determine what shaft it is.

But I replaced everything with a TRW-TAS power box and used a fixed column from a 98 T800. Wow-pricey I'm sure😎 1 Quote Link to comment https://www.bigmacktrucks.com/topic/63425-close-call-today-with-the-b-model/page/2/#findComment-456791 Share on other sites More sharing options...

That B-42 shaft only measures1.00” max over it’s length. So your’s is heavier like the B-73. Well at least we know it won’t fit. Sad part for me is that I was saving a really nice, crack free, 22” steering wheel from my B-42 for the B-73. I only recently took the steering column apart for paint and now I know it won’t fit, so back to the cracked one. Crap. Let me ask around to see if I can find you one.

I'm assuming he uses some sort of epoxy- someone on this site must have contact info for the guy.

j hancock Posted July 27, 2020 Share Posted July 27, 2020 I did my wheel with the kit available through Eastwood. It was fairly easy to do. From the pictures, I would say my wheel was a little worse than your wheel Matt as a comparison. My redone wheel stayed looking good for about 4 years before a couple of blisters started to form and hairline cracks reemerged. It's alive! I will pull it over the winter and do it again. I checked with someone to recast it many years ago and the price was like $400. 1 Quote JimIt doesn't cost anything to pay attention.

Popular Post Red Horse Posted August 10, 2020 Author Popular Post Share Posted August 10, 2020 Update! Or should I say "Lack of Progress Report". Had a friend over who is a recently retired very experienced HD mechanic-both on and off highway. He is going to help me-or should I sayI am going to help him. I got the trolly brake etc off steering column and the column free from dash. Then started getting floor pans loose. Finally decided only way that was going to happen was to get fender off. Figured in the long run it would be time well spent. Once I got floor mat/insulation up discovered a few "add on" plates that were done in transition from gas/quad to 711/ duplex, 237/duplex Stay tuned and as always welcome any and all suggestions. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/63425-close-call-today-with-the-b-model/page/2/#findComment-458086 Share on other sites More sharing options...

Luckily the carnage went out the passenger side of the transmission tunnel and didn't amputate his legs. i had that happen in my 64 bananacuda with a 273 engine that was worked. it was pushing a little under 350hp on dyno. flywheel came through the floorboards and took a section of my right leg as it went past and through the roof.

Truck Shop Posted August 10, 2020 Share Posted August 10, 2020 I think I still have the lower section and manual box from my B75 if any one is interested or could possibly use it. Free.

Old guy here but back in the 60's NHRA required a scatter shield even in the higher stock classes right??
