I want to use WordPress header and footer for OpenCart shop

Hi,

I want to remove OpenCart Header and Footer and I want to use Wordpress Header and Footer for my OpenCart shop. I'll add all OpenCart category URLs in Wordpress menu manually.
My Wordpress website URL is https://www.gethappythoughts.org/ and
OC URL is https://www.gethappythoughts.org/shop/
Please help me how I can do it.

Please help me how I can do it.

Well, this is a highly custom request, so better don't expect
someone, to invest a few hours on such, just for the plain fun of it.
I would place a posting in the commercial section, not all DEV's check
all postings in the open Section.
Good Luck !
Ernie
