Vacuum lines

map 87 gn

I'm looking at changing all of my plastic vacuum lines in my 87 GN. I was wondering if there is someone that sells the whole kit already cut or am I better to get it at the local parts stores. I am looking at something that will look nice under the hood since I am cleaning up the engine compartment this year. I was also wondering if you had the size of the different vacuum lines in the GN including the hard plastic ones (already broke 2 of them :( )
Thanks in advance for any info. :)
