What year of Chevelle? I have the 20403 in my 68 and also in my "70" (actually a 71 dressed out as a 70 ) It fit well in both cars. The 68 is a factory BB car and has energy suspension urethane motor mounts and the "70" is factory SB car with Moroso solid mounts.mdepalma said:I used a Moroso 20403 on my can and it didn't fit. Did anyone else have the same problem? It is to sqaure at the bottom of the sum and hits the crossmember.
