I assume by "metric Chevy" one is referring to 5x120mm PCD (Pitch Circle Diameter is the technically correct term) which IMHO (I have some experience in wheel engineering although not pass car specific) is different than 5x4.75 which is commonly referred to as a 5x120.7mm PCD. These things are usually referred to pretty precisely (e.g. the commonly used/referred to in industry 6x222.25 PCD on Japanese Cabover trucks such as Isuzu NPR/NQR is the old 6x8 PCD used on American Trucks back in the day - Still many UPS trucks out there w/it). Will it bolt up? Yes. Is it right? No. Do people do it? Yes, but people do all kinds of crazy things wrt wheels & tires that is incorrect & work, but dangerous nevertheless. Would I? No, unless I was stuck on the side of the road and it was all I had. It would certainly get you somewhere. Here's an interesting thread on the topic. https://www.thirdgen.org/forums/wheels-tires/738077-5x4-75-vs-5x120.html
Metric Chevy... Please post the article where you read that. I think that metric is referring to the lug nuts/bolts and not to the rims? That you have to use a metric socket on the lug nut or bolt. Because every rim has a metric size, just convert inches to mm. Bolt pattern in metric / Bolt pattern in inches (SAE) 3-lug bolt patterns 3 x 98 mm / 3 x 3.86" 3 x 100 mm / 3 x 3.94" 3 x 112 mm / 3 x 4.41" 3 x 150 mm / 3 x 5.91" 3 x 160 mm / 3 x 6.3" 4-lug bolt patterns 4 x 95.2 mm / 4 x 3.75" 4 x 98 mm / 4 x 3.86" 4 x 100 mm / 4 x 3.94" 4 x 101.6 mm / 4 x 4" 4 x 108 mm / 4 x 4.25" 4 x 114.3 mm / 4 x 4.5" 4 x 139.7 mm / 4 x 5.5" 4 x 160 mm / 4 x 6.3" 5-lug bolt patterns 5 x 98 mm / 5 x 3.86" 5 x 100 mm / 5 x 3.94" 5 x 108 mm / 5 x 4.25" 5 x 110 mm / 5 x 4.33" 5 x 112 mm / 5 x 4.41" 5 x 114.3mm / 5 x 4.5" 5 x 115 mm / 5 x 4.53" 5 x 118 mm / 5 x 4.65" 5 x 120 mm / 5 x 4.72" 5 x 120.6mm / 5 x 4.75" 5 x 120.65mm / 5 x 4.75" 5 x 120.7mm / 5 x 4.75" 5 x 127 mm / 5 x 5" 5 x 128 mm / 5 x 5.04" 5 x 130 mm / 5 x 5.12" 5 x 135 mm / 5 x 5.31" 5 x 139.7 mm / 5 x 5.5" 5 x 150 mm / 5 x 5.91" 5 x 155 mm / 5 x 6.1" 5 x 170 mm / 5 x 6.69" 5 x 205 mm / 5 x 8.07" 6-lug bolt patterns 6 x 114.3 mm / 6 x 4.5" 6 x 115 mm / 6 x 4.53" 6 x 120 mm / 6 x 4.72" 6 x 127 mm / 6 x 5" 6 x 139.7 mm / 6 x 5.5" 8-lug bolt patterns 8 x 139.7 mm / 8 x 5.5" 8 x 165.1 mm / 8 x 6.5" 8 x 170 mm / 8 x 6.69" 8 x 200 mm / 8 x 7.87"
If that's the case (obviously not how I took it), then yes, they'll work. The wheel doesn't really care if the studs/nuts are metric, just that the correct type of nut is used.
It doesn't say if this is about the rim, it only says "metric chevy", nothing like "5 x 120.6mm" or so. So that's why I asked for a link to the article where he read that.
