I did not got exact response to my questions but thank you all anyway
I probably will buy and take the risk and will try to drive with RWD

There was no comment to ebay ad for Trans case If drivebiality effected I might buy something like that and try it.

Other question is what do you think I should change with no special tools
I am thinking
1. Spark plugs (if necessary wires)
2. I don't know if it has distributor cab or something similar
3. Transmission flush
4. Injector cleaning and/or replacement
5. Air Filter, PCV Valve etc.
anything else you can think of will be great

Thanks
