New AC charge: weight, site glass or manifold

So what's the best method to do a new charge for the AC?
The manual says 1.3 kg--so, just fill that in and I'm good?
Replaced blown out condenser with new,same style, tube & fin
so volume should be the same. R12

Only condenser & rec/dryer are brand new.
New compressor a year ago--flushed and added correct amount of oil.
New expansion valve two years ago. PIA to put in!

I'm adding oil to the rec/dryer and with a can of R12 oil charge to
account for the new parts and sudden loss of freon.
Data guide says 70cc or 2.4 oz of oil.

Thanks,
Jeff

Condenser blew out. There was a cloud coming from the front of
the car--thought the radiator had gone at first. That was six months ago.
Waited for warm weather to fix it all.
