That's what we do here buddy....help out the fellow gearhead, and gain some knowledge in the process!!!
Another good site is dixie restoration depot. Just google it....they have a ton of stuff for the monte's...not so much for my cutlass
, but that's okay since I'm pretty efficient at sourcing parts with my thumbs lol!
Go to ebay motors, search for 84 monte carlo parts...filter down to whatever area of the car you are hunting for, and you will find yourself sucked into all kinds of stuff before you know it.
As you've done already, don't be afraid to ask questions....tons of knowledge here. I'm 33, but have had my cutlass since i was 17 so I've had some time to acquaint myself with the g body platform...and im still learning new stuff about it. Awesome back story btw, cool that you were able to find the car in decent shape instead of learning it was crushed years back!!
