I'd say it would work ok. I did something similar on my 33. Theorising about shock angles is fine but on the typical hotrod movement is normally pretty limited and we're not typically doing hundreds of thousands of miles. That said, the top mount in that pic looks pretty shot! If I were doing it I'd establish the shock angle and try and drill at right angles to that. (slightly downhill from the outside going inwards). Like anything, if you think it will work, try it. If it does work, great, if not try something else. It's a development process. Oh by the way, the most effective shock angle is vertical. Problem is, it looks a bit goofy. Mart.
