I need two sizes:

Can anybody tell me what size the fitting is that threads into the Intermediate line (body to Rear end hose)?

Any possibility that anybody knows what size the same fitting is on a 1999 Trans Am (all 98-02 f body)?

Here is what I am trying to accomplish. When I sold my 4th gen, I removed the later model brakes and put stock brakes back on. I have the complete Earl's Stainless Braided hose kit already, so I might as well use it (to include the intermediate line). I just need to know what adaptor fitting I need to thread the Late Model intermediate line into the stock hard line.

If you go to Napa and look in there Weatherhead section they have tons of brake adapter fittings. I'm sure you will find something you need. #1442 is very common in adapting standard bubble flare which is 10mmx1.00, to standard 3/16 inverted flare. I know thats the part number you need if you put 98 and newer rear disc brakes on a older vehicle.

I will probably take both intermediate lines up to NAPA and just figure out what I need. I used the 1442 for the front brakes (hard line to hose), but this one is a bit larger. I also need to have the hard lines bent to where I need them. should work out okay.
