One of the four hood hooks was missing; bracket was completely gone, just two holes where the spot welder joined it in 1945. So, made a new hook and bracket. Found a comparable spring at Feldman's (farm and home store--great hardware dept.) Had some 1/4" cold rolled steel rod to start with...
Cut out and welded bracket to inside of hood:
Next was the steering wheel. Had a devil of time getting the old wheel off. The PO had used electrical tape in an attempt to secure the rubberized grips from completely falling off. It took a lot of work to just remove the jam nut and I even stripped out a 3-jaw puller trying to get the wheel free. No can do. Hated to do it, but finally used a grinder with cutoff wheel to cut along the key way and split the steering wheel hub. It finally "popped" off, but the threads and end of the steering rod shaft were slightly mushroomed. Bought a 3/4"-16 die and re-threaded the rod and bought a new jam nut.
Went to an auction a couple years ago and bought 3 or 4 Farmall steering wheels; two were Cub size, two were bigger. Almost threw the larger ones away on several occasions, but now I'm glad I didn't.

Took the best looking one of the two and did some repair work (see How To here: viewtopic.php?f=11&t=37140). It only had one place that was really bad, so used the 2nd wheel to cut off a replacement piece(s):
Using a Dremel with cutoff wheel, I removed the pieces by cutting along the inside and outside edges, then across the handle. Then use screw drivers to pop them off. Here they are dry fitted:
I've found that two applications of JB Weld is necessary. Apply one coat, let set overnight, sand down. Apply second coat, repeat. Apply liberally to all the joints and cracks. It's easy to sand off when it dries. Here's the wheel dropped onto the rethreaded rod and new jam nut:
And the final product prior to paint:
The throttle plate was worn out, so needed to improve it (see How To here: viewtopic.php?t=16546, and here: viewtopic.php?t=28536). Fortunately, I had some scrap steel the same thickness. Cut a piece and bent it to match:
Old cut away, new welded in and all ground down smooth. Ready to measure and transfer the tooth notches from old to new:
Teeth marked and ready to cut:
Using my Dremel again (if you don't have one, you need one!) to carefully cut to the outside of the lines:
Also had to add some weld to the handle's tooth and reshape that. Now, complete and ready for paint and reassembly. Should last another 68 years.
