radiator caps

[wzehring@cmb.biosci.wayne.edu (Will Zehring)]

Fellow moggers:

Am I correct in assuming that the most likely preasure rating for the 
radiator cap on my '67 4/4 is 7 lbs.?  I can't make it out from the cap 
itself.  I'm going through the system renewing the PO's hardware (hoses, 
cap, thermostat, etc.) and want to 'do the right thing.'

Many thanks,
Will Zehring

p.s.  Zowwie: the rear main seal is *STILL* holding.
