That's is not totally true. I bought a set of 4:88 and put them in by my self with no experience. Make sure you have patients. And use the paint. It will show you where your gears hit. The more contact area you have the longer you gears will last and not howl. But also too much will cause resistance. put the gears in with stock shims. If they are not meshing enough add enough shims to make them mesh. If not add shims to get the desired result. remember you do not have to put the shafts in to mesh the gears. But also the pinion shims are a little harder. They must be torqued to spects. So that being said if the pinion shims are off you have to take it out and add or subtract accordingly.
