Grosbeak, there is another thread on here that shows a product called something like thrust shims. Three plates come in the pack 1, 2, and 3 degree plates. Maybe they could work for you. If one isn't enough, you can try another since they are the same size, so swapping them out would be easy.
LOL.....it's called Dave Brown Motor Mount Shims....... Right now, it is 3 threads below this one.
