I knew I was gonna get the "just use RTV", which is what I originaly planned on until I realized they used gaskets. I already looked up the gasket specs, and it is 1/32" thick. I know it isn't much, but it does have to have some affect on alignment of the axles in relation to the housing, especially on the front where there is a seal involved near the chunk. I'm scared to even ask Memphis, I'm sure they have it, but will want a fortune for it, and it's probably something they reproduce, not a military part. Worst case I will just buy some gasket material and make one. One reason I would like to keep the gasket, is it would be easier during assembly. It's not like you can apply the RTV then just pick the chunk up and put it in place, I have to pick it up and move it with my tractor. So, I'm thinking it would turn into a mess trying to use RTV.
