Im not sure about the sizes, but if you are getting the topper at a shop they should be able to get ya the correct size:great:

 

Oh no, I'm very much a poor man. I bide my time, till one comes along used, that's within my price range. I'm doing the same thing on a truck tool box. I'm in no hurry for either, so I just wait till I find one used. I'm cheap.

 

I understand, im tight with my $ too.

Somone else will be able to give ya some more help.!

 

werd. thanks anyway though.

 

dont they have a standard short box on them

 

I'm not sure. I don't know what denotes a short box, or a long box. I do know what a cardboard box and an Xbox is though.

 

You have 3 size's 8ft ,6.5ft,5.8ft. you have the 6.5ft bed just make sure you get the right year for your truck.

Right on, thank you. So is my measurement on the width correct, at 66inches? Thanks.

 

Any good shop should be able to tell you exactly what you are looking for, just give them a call, the least they could say is no. Google your truck like "1500HD dimensoins" or "2003 1500HD" I bet you can find it that way as well

 

Very true. I wasn't able to find it via google, I'm sure it's there, I just couldn't find it. And I could go to a shop, but I was more or less just hopeing somebody on here, would know. It's my understanding that all 1500HD's are crew cabs, and, again this I just speculate, but all have the same size bed. So I was just guessing that somebody would be able to say, oh you've got this. Without the hassle of calling, or driving to a shop to ask. savy?
