lowering links or lowering a GPZ

[Randy noneofyourbusiness]

What is the best way to lower the GPZ?
 
I got it on the road Friday April 2, & I have already managed to get in right at 300 miles, but my 26 inseam I am vertically challenged, I need to lower it a little.
 
right now I can only get 1 foot flat on the ground at a time, or both feet tip toes, so for safety, it needs lowering so I can get both feet flat on the ground. I am having problems turning it around on my driveway, which is like an old country dirt road with tall center hump, plus my driveway is up side of a mountain nearly 1/2 mile long.
 
what is recomendations? anyone have a used lowering link? or? 
 
Thank you,
Randy
