Question about Chevrolet Impala
This is a difficult one due to the many different sizes that are avaliable for this component.
The best thing would be to take the EGR valve in to an Autoparts shop and ask for the bolt size that fits the holes nicely. You will want it at least 1/4 inch longer then the body of the EGR valve.
By my guess you would be looking for a bolt sizes like the following:
1. 3/8 x 1/2 UNC or UNF
2. 7/16 x1/2 UNC or UNF
But the best option is to take the valve in and size up the diameter and lenght if the bolt. The thread however will be either UNC or UNF as above.
Hope this helps, let me know if you require further information

I do not know,but 8mm is used most,the length you may can figure out,but go to the parts house,and ask for2 bolts 8mm 1.25 thread,at 25 mm long,and ask for 8mm 1.50 thread,and 25mm length,and cover your bases,they are not that high in price,if some one has them,this way you can go by this,Look at the e g r valve to make sure you can get the bolts in the holes of the e g r valve,cause the heads of the new bolts will ,no doubt be larger than the ones that came out of it,the bolts are a general,or generic if you will,and will work if you can get them in the e g r valve,and use a wrench to screw them in,
