Part #196 - #197 - #198
These two photos show the difference between three of the four roofwalk patterns. Walkways shown from left to right are
#198 US Gypsum Diamond Pattern -
#197 Apex Slotted Pattern -
#196 Morton Round Pattern
The Transco pattern is different than the Gypsum in that it expands vertically vs. the horizontal of the Gypsum. Here
is a link to a view of a different car with a Transco roofwalk.
