My porch floor needs stripping and replacement of at least some boards. Depending on condition after I pull up all the boards, I am debating using composite T&G flooring. However, I am not finding any product available in 1-1/8" thick by 2-1/4" width to match existing floor. I am also not having much luck finding wood (fir) in 2-1/4" width. Two questions.

1) Any thoughts on mixing composite with reused existing flooring?

2) Any leads on composite (or wood) flooring in
1-1/8" x 2-1/4"?
