Think very carefully before getting an MBA. You'll run up heavy student loan debt, and without a few years of relevant experience you may well end up in an even worse catch 22 than you are now. Been there, done that.
The lateral arms might be worth doing if you can get them for a good price.
Read this: http://www.jalopyjou...ad.php?t=350800 regarding the acetone/ATF mix. I tried it and now it's all I use. Squirt it on with a 5cc syringe (the type you get at the drug store for liquid cold medication). Both fluids are fairly cheap for the quantity, give it a shot.
Try the following loosener: a 50/50 mix of acetone and transmission fluid. The acetone breaks down the rust and the trans fluid helps it seep in and keeps it slippery. And more use of the torch (heat gun works well too), plus get a bigger hammer.
