Now that we have achieved a proper tandem "fit", I have these parts for sale
Also listed here
http://www.gtgtandems.com/parts/stems.html, I have two stems for sale:
1-1/4" Santana Forged Aluminum Stem 90mm x 15 degree, 1" bar raise
1-1/4" Santana Forged Aluminum Stem 90mm x 35 degree, 2" bar raise
and one 2" stoker bar back.
The stems are for a 1-1/4" steering tube and (without a shim) will not fit the more popular 1-1/8" tube. Cannondale used these stems on many of its mountain bikes. Does the Cannondale tandem use the same stems? I'm not sure.
$125 for the lot or can be sold individually, plus shipping.
