Hey guys the ride on my G20 is to stiff for my sore bones. I want to put some springs from a G10 in it since I don't carry heavy loads. I need either a place I can order new springs from or maybe there is a van junk yard where I could get used ones or a member has got a set. Thanks Jackson

Hey there, Welcome to the site!

Only one of these yards is close to me, but 3 may be closer to ya'll. A good resource for used parts.
Good wrenching on your Chevy, and Kind Regards from West Texas!

According to Rockauto, they use the same front springs, MOOG 6452.

That's the same thing I found under Moog......
6452 for G10 and G20
6454 for G20 and G30
6560 for G30 only
You may already have the larger/heavier springs from the factory. Check your wire diameter on the existing springs. If it's about 0.82" then you have the heavy springs and the 6452 will be softer. The 6452 wire diameter is about 0.78". The GM G10 springs (softest) are 0.75" if you can find 'em in a junk yard.
There's no difference in the free height between 6452 and 6454 just the wire size.
The 6452 is rated at 3155 pounds while the larger wire diameter of the 6454 is rated at 3840 pounds.

Thanks guys I was surprised the coils might be the same, it seemed my 92 road smoother than the 95. I don't have a good way to measure them right now, so I'm going to give this information to my mechanic. He was gonna lower it for me with spindle & an axle flip kit. He said he could take the last leaf out & that would make the back ride smoother.
