Tee Top too tall!!!

[fdheld34]

My Tee Top is way too tall for me. I am aware standard height is somewhere under 7 feet or a little less?? I am only 5'11"
How could I lower this tee top??
I had a person give me a price of $300 to lower for my needs..seems steep to me.
Any ideas how I can do this myself?
I was thinking of cutting abpout 5 " off of four support pipes and then adding larger diameter pipe over existing cut pipe ..like a sleeve to join together and using bolts to secure?
or a step stool if I wanted to use rod holders!!!
All help appreciated..
Also thinking of getting rid of tee top altogether and just going with a bimini??
Thanks in advance
