Genuine Denso starters are pretty expensive, so I decide to see if I could find replacement parts. It seems there is good aftermarket support. I was able to find replacement plunger and contacts on Amazon from multiple vendors. I just wanted to make sure they were the same as what I needed, so I ordered a set that had two options and it fit very well with some tuning. I tested the starter and it works great. $20 vs. $300 new, unless you buy a generic.
