Based on my limited research there are at least 4 variants (based on 2wd/4wd and the original motor) of these mounts. Looks like they run from $42 - $83, again varying based on your original setup. Anything other than the 2.8L V6 is $70 or $80 + shipping, so I guess your figure is about right, at least based on s10v8.com pricing. Doing these mounts seems more involved because most of them would require being packed with rubber or urethane (something I haven’t looked into sourcing though I know the CNC shop can get just about anything), but I’ll keep it on the list and certainly consider it for one of the first designs, so thanks.
