4, 5, or 6 spike?
If you look there is a thread floating around somewhere with patterns for spikes, I think I put copies of the standard 4 and 5 tooth Mac spikes in there.
If you can't find it send me a PM with you e-mail and I can send you a copy so you can make your own.
Bob Johnson (Bob's Lawnmower Service, Maryland, NY) probably has the 5 tooth, I think I have all his 4 tooth.
Not sure I want to sell any NOS ones that I have, but then money talks!
The same one works from the D-44 all the way through the SP125, including D-30 series, all the 1-40, 1-50, 1-70 series, 200/300/400/500 series, 700 series, others I'm sure I've missed. Basically all of the large frame/large bar direct drive saws use the same part numbers for the spike bar.

Yeah, I have a few...
