Here's the original steering wheel in my 1988 Cab Plus SE, still on my truck:
Here's two three-spoke steering wheels I picked up at the parts yard Saturday. Note that the one on the left is missing the Mazda logo, otherwise fine.
By the way, I did make a logo yesterday at lunch. I got an old Mazda logo off the Internet (blue on white), pasted it into Paint, inverted the colors to get orange letters on black, pasted that into Word, got the size right, then pasted that into a Word page set up for Avery adhesive labels, then printed it. I cut that out pasted it into the slot, then covered that with clear 2 inch tape, and then used my knife to trim that, see photo below.
I'll have two of these steering wheels for sale, all in nice condition, after I decide which one to keep for myself. I'm leaning towards the 3-spoke for which I made the logo, above, like the nice round horn button !!!
