If you have either the 130 or 142 tooth flywheel it is a bolt in and use, if you have a 170 (173?) tooth with the direct drive starter your SOL(solidly out of luck )I used both both brands, Lakewood and Ansens in my 1970 Cuda with a 1968 street hemi motor that had the 170 tooth flywheel. I had to switch to a 142 tooth flywheel and the gear reduction starter to use the first ansen scattershield I later switch to a 130 tooth flywheel with the 10.95 clutch and pressure plate. several things come into play, the Z bar mounts, the front bearing size and the throw out arm. All of the Z bar mounts I have seen unbolt from the stock bellhousing and bolt correctly on the scatter sheilds Both of the scatter shields I had came with adapters to move the starter and a adapter ring to insert in the front of the scatter sheild to use the small front bearing transmissions, I ran a 18 spline trannys with the large front bearings so I didn't use the adapter rings, I still have one
