Most use the Lokar units. I think I got mine from Fabulous Firebirds in Missouri, but I see their link no longer works.
OK, you don't specify which of the two above is the F-body stick...the silver one looks just like the one's I have looks Which I believe to be correct TH400 F-body dispstick tubes - does this look correct?
If it is a Firebird dipstick tube how much is it worth?
