Hiding price, quantity and Add to Cart in ONE STORE on 7.1

I have a site with TWO DIFFERENT STORES in it. Using squarespace 7.1

In only ONE OF THE STORES, I need to hide:

the price

the quantity box

the Add to Cart button

Please help! I will need to know the exact code and WHERE to put it in a squarespace 7.1 site. Everything I have tried has failed and mostly of what I find is only for sites NOT on 7.1, ie NOT using templates.

In the Products Settings menu of the actual store page / Advanced / Page Header Code Injection / 

This code works: 

<style>
.product-price,
.product-quantity-input,
.quantity-label,
.yui_3_17_2_1_1586294340112_457,
.sqs-add-to-cart-button-inner
 {
 display: none;
}
</style>

But only removes the PRICE, the word QUANTITY (but not the box graphic or number in it) and removes the 'Add to Cart' text but leaves the color bar. I have also discovered the small 'cart' graphic at the bottom that i also need to remove now.

See screen shot.

Can you share link to product page?
