I researched and found that I can find the 'part#' in view.phtml in app/design/frontend/default/mencom/template/catalog/product. The most relevant row I could find is
<div class="product-parts"> <span><?php echo $this->__('SKU');?></span><?php echo $_product->getSku();?></div>
All I want is to add a space between 'Part#' and SKU(T35-...)
Thank you for your help in advance.
