Drivers who won features in both a modified and sprint, both built by same builder:

Dick and Scott Tobias- Tobias chassis. Ironically Dick won modified features in cars built by others, and Scott did the same in sprints.

Kenny Weld, both built by himself.

Jimmy Horton- Tobias chassis.

Stan Ploski- Buckley chassis, 

Bobby Weaver-Weaver chassis. Bobby also once won the modified and sprint features at Port Royal on the same night.

Gary Gollub- Tobias chassis. I’m told that Gary also won a modified feature in a Weaver chassis for Bill Brian but don’t think he won in a Weaver sprint.

Bruce Thompson - Buckley chassis.

A few “close but no cigar”. Drove both by same builder but didn’t win in both. Lee Osborne, Kramer Williamson, Kevin Collins, Freddy Sabatino. 

A couple “gray area” honorable mention: Gerald Chamberlain won features in both modified and supermodified built by Gus Frear, and Doug Wolfgang won in both built by himself (the sprint is called a Trostle but Doug designed and built it, and a South Dakota modified doesn’t really resemble an East Coast modified. 

There were more (and more possibilities)than I initially thought, thanks for replies, and feel free to add on.
