Need source for non-standard 2.5mm jack

[Robert Johanson]

I have Motorola SX700 two-way radios which i plan to use on
motorcycles.
I am modifying the inputs and need a source for the 2.5 mm male
"stereo" jack that fits into the radio that supplys mic and speaker
input. Standard 2.5mm male jacks are shorter
then the ones used by Motorola for their radios...
I need to find a source where I can purchase the 2.5 mm jacks that
will work with the radios....very slightly longer.

thanks
