I know this is just extra information but the 97 Del Sol VTEC B series linkage is about 2 inches longer than the 99-00 Civic Si or 94+ integra B series linkages. When I swapped the B16A2 into my 6th gen civic I had to cut 2 inches out of the Del Sol VTEC linkages in order for them to fit my car.
Conclusion: Del Sol VTEC B series linkages are 2 inches longer than other B series linkages.
