So you have the connectors to plug into the stock LT1 rail fittings or you have welded -6AN fittings to the rails as many have done?

You need these to adapt the metric O ring fittings on the original TPI lines to -6AN .

Early TPI cars have 16mm on supply line and 14mm on return.Confirm you have to different sizes before buying; someone could have fitted a later rail that has 16mm on both.
