Grob 103 - Main Tire Tube Type

Trying to order a 600 x 6 Tube for the main tire on a Grob 103 Twin II, and need to know which tube I need to order (which valve is used? ) There are several different types?

http://wingsandwheels.com/aircraft-parts/tubes.html

These are the valve variations:

TR-87 short valve bent out 90 degrees from center (left)TR-67 vs TR-87

TR-67 long valve bent out 90 degrees from center (right)

TR-20 straight valve

90 valve bent out 90 degrees from center

45 valve bent out 45 degrees from center

Thanks for the help!

I have a 600 X 6 tire and tube off a G-103 and it has a straight filler tube located 1" from center line and it is 1.75" tall.

The previous owner of W&W could tell you what you needed. That "corporate knowledge " did not transfer with the company,

According to my records our club orders
"TU 600-6 Short Tube, Short 90 Stem TR-87" tubes from Desser for our Grob 103 main wheels.

Note that there's also a fair number of Twin Astirs out there with the
optional mod for a 5.00x5 wheel. Mine is one of them.
