the 2 upper bolts and the lower rubber mounts what did the look like. if anyone has a picture that would be wonderful thanks steve
7/16" hex head with a small washer. If you are not a purist, you can use the same ones that hold the steering column firewall mating plate to the firewall....those are 3/8" hex head with a slightly larger washer.
Steve, I know the correct screw for a 71 is part #9421985 which is a qtr inch tapping thread with loose washer. I believe 70 is the same. Cehck the assembly manual if you have one. For a picture where you can buy brand new ones check out this link. They are on page 73 of the catalog. Nothing better than new. http://www.amkproducts.com/Catalog_PDF/72-89.pdf also the lower area on the core support had rubber sleeves that the shroud fit over
