I just retired after working for the last 40 some years and am still trying to figure out this retirement life style.
Congratulations on retirement. I got a paper that said I was 6 years ago but they keep dragging me back part time and I haven't completely managed to break the last links. I guess I'm a failure at retirement.

Like so many things, what it takes to convert to a fairly authentic appearing street car is a matter of how far you want to take things. It's both complicated and simplified by their being a few different models of 427 street roadsters - mostly variances in the engine and in the rear fender flare. The earliest street cars used basically a fully flared rear fender that was not a lot different from SC cars I believe. Then Shelby had them narrowed to better fit the width of the standard 7-1/2 inch wide Sunburst wheels and tires that were installed on all 4 corners - these are called the narrow hip cars. These are not commonly replicated although I think Kirkham does. A Cobra painter - Metalporphous converted an ERA to a narrow hip 427 car a couple years ago and made molds of the fenders for duplication. After awhile, Shelby reverted back to the wide hip fenders for the remainder of the street roadster run. Even in the wide hip cars there were some subtle changes in wheel lip flare and taper in at the front down to the rocker. There were also some minor changes in the rear flare of the front wheel wells.

AC bodies were typical of many English roadsters of the era in having a curved rocker panel profile - or exhibiting a slight belly. It's not apparent on SC cars because of the exhaust and usually no one tries to replicate it (except Kirkham). It is visible on a Street Roadster but very few you will find attempt to replicate it. Metalmorphous did so on the ERA they converted to a narrow hip car. I did so to some degree on my car when I built it although I probably don't have as much belly in it as the originals. This is one of those almost off the deep-in details that you have to think about how far you want to go.

The scoopless hood, lack of roll bar and undercar exhaust have been covered. The street cars had a different dash instrument layout and a glove box. The seats were leather where the SC cars were vinyl. The street cars had a different gas cap - basically a BSA motorcycle cap that sat flush on the fender instead of being partly recessed. They used chrome over-riders and usually chrome hoops for bumpers. The earliest cars used rectangular tail lights and the later ones had the round - quad tail lights.

Then starting to work further down into the minute details they had a vinyl pocket across the rear bulkhead of the cockpit for storing the side curtains. The rear bulkhead was vinyl covered. Everything else was carpeted. As far as I know Smith gages were used on all 427 Street Roadsters. If any SW gages were used I'm guessing it was on a few very early cars. Some cars had the reverse wind 180 mph speedometer but some had a regular wind speedometer also - I think also a 180 mph unit.

The was a unique finger grab knob for the glove box that can still be found. Some very late street cars did not have the oil cooler scoop under the front - but most did w/o a cooler. Most street cars had a single, 4-blade pusher fan in front of the radiator (not the twin fan set up most see). There was a unique Trico windshield washer bottle under hood. I think they used the 3 Girling fluid cans for brakes and clutch - not sure if there was variation in this or not. The 428 cars used a police interceptor intake with a Holley and were typically Ford engine blue. The 427 cars were actually mostly single four barrel Holleys - not sure what intake they used. The 427 motors were typically painted black. I may be mistaken (probably are) but the earliest street cars used what was basically a 1964 spec low riser, 427 center oiler engine - pretty much an R-code Galaxie engine and they may well have used the dual quad intake from it.

And after that you can really dive off into the truly minute details - location of battery, location of voltage regulator, location of starter solenoid, Lucus components for underhood wiring, straight slot mounting screws, etc, etc.

One thing seems to hold - there were exceptions to just about everything, Cobra's being essentially hand assembled cars and parts being constantly sourced by Shelby or supplied by Ford and being somewhat variable. And then Day 2 changes were probably so frequent that a 6 - month old Street Roadster could have any number of changes made to it already - so what's original and what's custom? Few are schooled enough in the cars to know (many of them on this forum however).

This probably confuses more than it helps. You can capture the essence of a 427 Street Roadster with about half of the above. The rest is just personal obsession.
