[jiggs]

im looking to buy an s13 vert but it has some problems mainly the top
it doesnt want to go up or down
the owner says the baby window track is broken?
i would rather just replace the whole mechanical setup with the top
what are some things i should look for first before i do anything?
where can i order some oem nissan parts for the top and etc?

btw i searched already and it showed up mainly verts for sale
any help would greatly be appreciated.
