Mazda B2200 window swap...

Guys I'm look'n to see if anyone could give me some quick tech advice of how to remove and reinstal the back window of a Mazda B2200 late 80's model....

Any help would be useful to me...

push the gasket out from the inside, start in a corner and work around. to install wrap some string around inside of the gasket and lube with dawn dishoap, pull gently on string and work it into place

use wd40 and press it out the back gently. installing use a small rope and pull the gasket in from the outside.

Thanks a bunch guys
