help best way to check chassis aligment?

[baz-r]

if you have read my other post you may know i suspect the chassis i have just borght of ebay has been made incorectly but cant be sure where the prevous builder went wrong

i think im getting about 3-4mm out of parellel on the bottom tube of the frount frame

makes me think if this is wrong the whole front suspension will be on the wonk not to mention what other mistakes have been made

i was thinking of building a build table and marking it out to see if i can see where it went tits unless someone has a better idea

i can see some mods have been made to the trans tunnel it looks off set to the passingers side to take a bike engine that will need unmoding

im also finding the short pice of box attched to the chassis plate that takes the top of the shock has been missed out

dam i should have bided on that talon s/h one!

handyandy if your reading this im going to need som odd tubes and cp's if i make a list you rekon you could come up with the goods?
