With either trans we’ll try to use the stock boot setup to look like a factory 4 speed. LMC has the boot and a floor seal. I’m assuming there’s a floor panel/ring setup? Can someone post pics of what the floor panels look like that has 4 on the floor?
Thank you very much

Where does this one go on a 4 speed?

Looks like this one goes in the hole for the floor shift panel to seal the shifter handle. I got it sorted now. Thanks for the help.
