Thanks for the informative replies, all...

Yes - as I said on another forum; my mileage numbers were hopeful at best, asinine more realistically...

I may try and pull apart the speedo at some point and remedy the issue. Of course, it also has 16" Lorinser Type 90 wheels, which will introduce another variability into the system since the car wasn't geared for the larger wheel/tire combination.

My assumption about the rear glass being extremely delicate in it's current state was indeed true - and removal would most certainly result in a thousand little pieces...

I'll have some time to devote to it once I get my clutch back into my pickup. Can't afford to have two down vehicles.

Again,

Thanks.
