The values are printed on the components. Space will become an issue as new film caps are considerably larger. For the two 130uF caps you will have to use Solen. For the other caps, Sonicap Gen I or Clarity CSA are good choices. For resistors, Mills or Vishay Mills.
Forget the eBay guy unless that is DHS Speaker Service, who is westmassguy here.
What Jesse said about space.
The two black 130uf caps are replacing the two blue 130uf caps at the bottom of the pc board pic... to give a size comparison.

This should always be the first place to look for crossover components as well as other speaker related items.

lol ok you told me the component values are on the components. and now you change the rules lol I have all the other resistors in my cart at sonic craft but I was only looking at the 5watt resistors. so I can use the 12 watt? -
Yes you can, most of us do move up in wattage (in resistors) while keeping the ohm values the same. It's cheap insurance so to speak.

ok I have my parts list as follows
crossover parts list
capacitors
2/ 130 uF
2/ 20 uF
1/ 92 uF
1/ 12 uF
1/ 4.4 uF
resistors
2/ 22.5 ohm
1/ 15 ohm
1/ 7.5 ohm
1/ 2.7 ohm
all the capacitors are Solen Polypropylene Capacitor
but I could not find the 4.4 ones using solen. so I found a 4.4 using sonicap
I could use all solen caps if I use 2/ 2.2 uF caps. is it going to hurt anything to use the sonicaps
for the 4.4 ? -
also could not find the 92uF caps. so using 1/ 82uF and 1/ 10uF together
total cost $700 to do both crossovers -
Never use Solen except for the shunt circuit.Political Correctness'.........defined

ok all sonicaps?

ok all sonicaps?
Just the 4.4, 12 and 20. You'll have to use Solen for the others.Political Correctness'.........defined

ok wow it's over $1,000
-
ok and I will be ok using the 82uF and the 10uF caps for the 92uF ? -
ok wow it's over $1,000
What!?!
4.4uF x 2 = 95.60
12uF x 2 = 111.20
20uF x 4 = 275.68
Total = $482.48Political Correctness'.........defined

Parts Connexion has Solen PB caps.
It's best to split values as equal as possible. Otherwise, you could use a 91uF and ask if they can find some closer to 92uF.
Their prices are considerably cheaper than PE. For example, the 130uF is $45.76 compared to $79.30.Political Correctness'.........defined

the $1,000 is total for everything for both crossovers from parts express and sonic craft. but the 12uF caps are on back order from sonic craft anyway. i'll go look at parts connexion

ok my inventory so far sonicap said they won't have the 12uf caps for at least 3 weeks. also can't find the 7.5 resistor in the mills vishay. but they have them in the mills MRA-10 what is the difference and can I use the MRA's? so I could use just a 91uf cap? or the closest I can find would be a 36uf and 56uf
-
The MRA 10 watt is fine.
If it was me I'd go with the 36 and 56.Political Correctness'.........defined

OK got tweeters installed I am now looking at updating the crossovers. can anyone tell me if these caps look bulged or were they just made that way.
Even if not bulged or leaking capacitors loose there value after years. Capacitors last about 20 years and need to be replaced.
