1988 R30 VIN Frame Location(s)? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Ford Assassin · 06-11-2019, 12:54 AM

Hey guys, bought an original California Truck, but it has been registered out of state for the last decade. Took it to the DMV for a VIN verification, which it failed due to the door VIN GVWR decal being faded beyond readable. So, unless I find someone that will reproduce the decal (thus been unsuccessful), I am forced to have the CHP do their inspection which includes finding the frame VIN. Although I have little doubt the truck is sitting on its factory issued frame, I was warned buy the CHP inspector himself that if it doesn't match, I will not be leaving with my truck.

So.....where should I be looking? My Internet searching has been unfruitful. I didn't see it anywhere on the passenger upper frame rail facing the bottom of the body, at least not in forward of the passenger side fuel tank and the firewall.

The truck is a square body 3+3 (crew cab) dually. 2wd.

I appreciate any help in advance.

Edit: The dash VIN plate is clearly readable. CHP wants to see the frame VIN.

VIN should be located in the dash on the drivers side at the base of the windshield

On both my 88s (one R30 and other one a V30) the frame VIN is on the top of the passenger side frame rail right by the fuel sending unit. My 84 K1500 and 87 R10 has it in the same place also, so it should be there.

Can you confirm the final assembly location of the trucks you've mentioned here?

The original poster's crew cab would have been built in Flint.

Edit: I just realized when I ran the area that stamped the VINs: it was Flint Line#2 (Blazer and Suburban). That might be why I can never remember where it goes on the pickups, which were built on Line 1.

Keith,

The only one I know off the top of my head is the V30, which is a Janesville (sp?) truck. I had to go thru the same with it as it hadn't been registered in 10 plus years and the owner before me had passed.

I am on vacation so don't have the VINs in front of me, but will try to remember to check when I get home

This is more my curiosity - are they not able to use the VIN that is on the dash for verification?

California VIN verification requires TWO metal stamped locations. First being the dash. The second being the frame.

I have a frame from a 1987 K5 Blazer, the VIN was on the passenger side of the frame

**hatzie** · 06-12-2019, 08:32 PM

The frame VIN is often only a partial.
Hopefully they aren't expecting a full VIN

sweetk30 · 06-12-2019, 09:12 PM

there mostly looking for the build sequence as the rest is kind of normalish i would think .
