90q- Lower crank bolt removal

[jDolan]

I'm about to replace the broken timing belt on a 90q, and have read about
the specific tool required for holding the motor stationary while the
high-torqued bolt is removed from the crankshaft. Are there any
alternatives/procedures, or will I need to find this tool? I am working
without the benefit of 'air tools.'
 If it is required, is there anyone somewhat local that might briefly loan
it?
