Parts for AWD, Using a ST185 Options

[MaskedMan]

Ok well i had a question and have been doing some thinking. If i have a full ST185 to take apart, would that mean i would have most of if not all of the parts needed to do the AWD conversion to an ST204? I'm assuming i would have to buy new suspension though as im not sure the ST185 shocks will bolt right up to the ST204, but i haven't tried yet. Well the reason for this being is that basically some of you know i have an Alltrac, but recently, it appears that my engine had seen it's last day as i checked compression on it and it's like 90, 30, 30, 60. The chassis also has quite a bit of rust on it, and probably isn't going to last too many more years. So i am willing to just cut my losses and use whatever parts on it that i can, since i doubt i will be getting much for selling the car as a whole right now.

Well last year when i was going through checks with my engine, my compression was 150psi on all cylinders. So it was doing ok, but not the greatest. Seems odd that all my pistons would lose compression at the same time, becuase i was driving it on the road when it decided to shut down on me. I believe the engine could still be salvagable, but the cost estimate is really bothering me since im not exactly sure what the problem could be or if it's even worth to fix it. I'm kind of hoping it's just the headgasket, but right now im not exactly sure what i should even do with the car....
