Thanks for the reply Dan.
I've been reading your tutorial for a few months now LOL. Excellent work!
I also appreciate your input, I'm glad to hear it should work from someone who knows more than me (my local upholsterer didn't seem to
)
I do have the lower sail panel tack strips, I removed the whole inner 1/4 to make the new window guides.
Once I get the fuzzies and stuff installed, the inner panel will be next.
