Hey guys,
I'm Ben with Dapper Lighting. I don't have the dimensions on me but they are roughly 1/4-1/2" longer (with a bulb installed) on the back side. I'm not familiar with the sugar scoop/non-sugar scoop terminology but I'm assuming the (non-scooped) later 911's use a H4 bulb as opposed to the (scooped) sealed housing bulb. We successfully fit them onto a 1981 911 with 55W ballasts.
I apologize for the bad pictures but this is all we have as of now. I have driven the car and can tell you the difference in light output was amazing and had a nice crisp clean cutoff.
The only problems with installation that we ran into is that a new hole needed to be drilled (or the existing widened) from inside the vehicle's headlight housing to run the additional wires under the hood. It took us about half a day to get everything working perfectly. High/low all functions properly with the headlight stalk.
Please let me know if you have any questions.
