Re: How much would it cost/Did I make a good purch
I will echo and emphasize, a little rust in the floors, not necessarily end of the world, do check the rest of the car thoroughly, most common serious rust point on these cars is on the rear spring mounts, so check these, expensive fix to do right, and not safe to drive if they are about to come off and the springs are also the rear axle locators.
Check the rocker panels as well, you might try a week magnet as well, which can tell you where thick bondo or bondo with no metal underneath lurks.
Give ot the good once over and if it seems safe, tune it up, drive and enjoy.
Clutch sounds like bad hydraulics to me, may be able to get by with a master and or slave cylinder rebuild kits, which are pretty cheap, inspect all the brake hoses as well, should be three, one to each front wheel and one to the rear exle, replace if they look old, swelled or cracked.
Have fun, neat looking car, bugeyes look good with a stripe or two!
