how would i match up these 2 film capacitors, i believe they are metallized, newb here

#1

#2

and what is this steel plate

 

0.68uF 10% 250V (First two digits are the significant figures and the third the number of zeros to give a pF value, 680000pF=0.68uF, K=Tolerance and I think 250AC rated)
1.0uF 10% 250V (1000000pF=1.0uF, K=Tolerance and I think 250AC rated)

 

0.68uF 10% 250V (First two digits are the significant figures and the third the number of zeros to give a pF value, 680000pF=0.68uF, K=Tolerance and I think 250AC rated)
1.0uF 10% 250V (1000000pF=1.0uF, K=Tolerance and I think 250AC rated)

ty, thats what i tghought after doing some research just wanted to confirm.
the 250ac im assuming is a non polarity rating of 250 volts, and i could do a 400volts to replace it?
the steel plate in 3rd pick was beside the cap but idk what its purpose was and if it got scorched because of the bad cap or if thats just the way its supposed to look like

 

400v is fine as long as it physically fits (read as room to put it in)

does the metal plate actually belong there? unless its something thats supposed to stop something from touching around the area. normally you'd have insulated material around high voltage
