1999 Vectra Grand Tour catalytic converters stolen

[LetsCook]

All -
I recently had the cats stolen out of my 1999 Vectra GT (model VCM37B). I've already talked to my insurance, and it seems as though due to previous claims, they may raise my rates if I claim this. The deductible alone wouldn't be worth it. What I was wondering is if anyone has the following two things:
1. Looking for a diagram that shows details of how the cats are laid out and how they are connected. The engine is listed as a Chevy 7.4L V8. What I'm alternatively looking for is maybe someone has this exact model motorhome and could possibly take a few pic's of what the cats look like and how they are mounted. I would take pictures, but like I mentioned earlier, someone decided they needed my cats more than me. Nothing left to take pictures of.
2. Does anyone happen to know where I can find the cats online? Places like AutoZone, Rock Auto, and O'Rielly do not list Winnebago's as a viable vehicle. I can't look it up by engine type alone, either. The Winnebago website does not offer engine parts. When I do a specific Google search for 1999 Winnebago Vectra GT for cats, such a wide array comes up that I can't tell what's right. Even just the model number would be a huge help! Or, conversely, does anyone know if "universal" ones would work? We don't have any long-distance trips planned, probably just 200-mile ones at most. Gas is just too darn expensive to do anything further right now!

Any information would be greatly appreciated. I'm thinking this might be something I can DIY, unless anyone might advise against that.

Thanks for reading! Happy RV'ing!

I paid 2.61 a gallon for regular unleaded yesterday.

Is that a P32 chassis? You might have better luck searching using the chassis model. That P32 chassis was used in a variety of applications.

You may have better luck using the chassis make/model. The cat converter isn't a Winnebago part - it was part of the motorhome chassis that Winnebago bought to use as the base. Since you have a GM 7.4L gas V8, I'm pretty sure you have what is known as a "P32 chassis". Or somtimes just "P30". It may be a Chevrolet P32 or a Workhorse P32, since Workhorse bought Chevy's motorhome chassis business in mid 1999. The cat converter is identical in both brand names in the 1998-2000 years.

That's what I just said: "Is that a P32 chassis? You might have better luck searching using the chassis model."

More than likely a P12 chassis. Which isn't going to be much help. It had two, like most Chevy powered motorhomes, right (you did say "cats...")? Probably going to have the best luck knowing the pipe diameter and GVWR. Something like a 3" inlet/outlet rated for a 10,000 truck (times 2).

Try a smaller auto parts that caters to mechanics. I had an old P-30 chassis that I used as a work truck. Didn't show up on most parts lists as it was a retired post office delivery truck. A small local auto parts was my go-to for anything that I needed. Mark, the owner, could not be stumped by any request. One time, I needed a weird power steering hose. He located one in NJ and had it overnighted to me.

The chain auto parts couldn't even locate the normal maintenance parts. Maybe go to a truck repair shop and ask them where they shop.

If the cats are prohibitively expensive, you could look at just straight piping them. There are obvious legal downsides to this put could be a good "plan C".

I hate a thief.

And I agreed. Is that a problem? There are often conflicting replies, so isn't it valuable for the OP to learn which one has more support than others?

Nice! Where do you live? AZ is still 3.29+ a gallon!!!

Agreed. The storage facility where I store it had someone "jump the wall" and hit several vehicles. Society can be such a pill.....

That's about $.50 lower than a year ago this time (nationwide average). Apparently you haven't had it out in awhile.

You were being redundant.
