Hi,

I'm the very happy owner of a new to me 2002 Chev Express extended hi top cargo van with a 4.3L. The van only has 68,000km (43,000miles) but it was probably parked in grass and it ended up with a completely rotten frame. That's why I got it for next to nothing.

I'm now shopping around for a replacement frame and was wondering what years of frames would be compatible. I know that the front end sheet metal changed in 2003 but has the frame remained the same? I found an 2004 van with a good frame, 4.8L engine but body is done. Hoping to make one out of the 2. Any ideas if it's a workable swap?

Day 1 of project.

 

The GM Upfitter manuals provide all kind of specifications about the frame.

You should be able to compare 2002 and 2004 measurements.

 

Wow. That is awesome. Thank you so much. This will save me a ton of heartache. Now I just need to figure out what I have. LOL

 

Update:
First, again thank you to mountainmanjoe! I read a few of your posts and it is obvious that you know your stuff.

I checked the data and compared the 2002 G217 (what I have) with the 2004 G237. (what the junk yard told me they had) and found out that from a top view, all the body mounts are in the same position which is a good thing. From the side view, the heights of the body mounts differ slightly. This shouldn't be a bid deal since it can easily be adjusted with the correct thickness spacers. The variations are very small.

However, it turns out that the junk yard did not have a 155" wheelbase but 135" so I'm back in the search...

I will keep you posted.
