I am looking for a used topper , and trying to see what fits what , between the different makes of trucks , Ford - Chevy- Dodge & yr to yr .

 

I do not know all of them, but they are diffrrent enough that you proably want a "Dodge" LB/SB topper. Get your dimensions and check Craigs list.
Call whoever looks good & have them measure it before going to check it out.
I also have a Nissan frontier, and only a Nissan Topper fits.

 

Well I bought one for my 95 and went to put it on and found that chevy has to be mod. The front of the box is 1" wider than at the tale gate. So measure your truck and the only one I know is dodge to dodge. hope this helps
