I admire your persistence. Maybe you can give some advice. I am sixty six and doing a very similar installation. It is finished. My problem: the wheels are farther apart at the bottom than at the top. The instructions said to cut 3/4 in off of two matching parts. The parts were to be removed, cut and then re-installed. I can not remember which matching parts to cut.
I do not have a problem putting short term memories in my head. I just can not remember where I put them.
Thank you for any help that you can offer. LinwoodC
