So does do the 205 and 200 blocks take the same sump gasket kits and thermostats?

I understand the 200 block that I have is from the later model 4x4s but I cant find any sump kits for a 4wd, only 2wd so am I safe in assuming they are the same? Ditto I am after an 83 deg thermostat but seem to only be able to find the 2wd thermo stat.

Thanks for your help...not many places locally can answer these questions and phone calls to the UK get expensive
