If the secon method doesn't work you can try, being very careful, raising the front end with a jack, put stands under to support the brat's front wheels off the ground. Hold the clutch pedal down and crank the engine in gear, you can try different gears, make sure you are NOT in 4wd. Now the engine is running, front wheels are turning, get your engine revving up, not wide open but be generous, nail the brakes hard. It is probably best to wedge something against the cluctch pedal to keep it down do you can hold the gas pedal and hit the brakes at the same time.
Last resort and most dangerous method will be to get a second person to lift the front of the brat off the ground at the front, put it ins reverse and crank it. Engine is running with you in it of course, clutch pedal is pressed to the floor, engine is revving, front wheels are turning, use reverse only so you don't go forward because the other person is going to be in front of the car and will drop the car suddenly. You don't want to run over your guy with the jack. Be prepared to run backwards quicky.
Hopefully tour transmission will survive these shocks and be okay.
If none of this works then your only alternatives are to pull the engine and put a new clutch in, be sure to get the flywheels resurfaced or sell me the brat really cheap ;-)
Seriously, be careful man. Its not worth wrecking or getting hurt. Don't do it if you feel its too dangerous. You are responsible for anything that goes wrong, including damages, injury and death not me or anyone else on here.
That being said I'd love it if you could get some pics of that roof rack. I want to custom make one for mine.
