doh! :homer:If you meant what "are" those lines, they are probably air lines.
ummm... mebbe i dont spell or type too good but im pretty sure that mount is to support the seats or the new tranny tunnel or something,not the floor supporting the tranny. wow...Are you mounting the transmission to the body with that cheezy looking piece of flat bar?
I truly hope that is not permanent. You need to build a lot beefier mount if you expect that to last, not to mention not wanting it to rip the floor out of the truck.
anyway,im thinkin we should prolly let the man finish up his build thread before we criticize.
