All non-supercharged cars use:
- Upper radiator hose 4S1230, at 1-1/2 inch by 7 inch
- Lower hose 4S1247, at 1-1/2 inch by 11-3/4 inches
- 4 clamps 7S10 to secure
Supercharged cars, including speedster, use radiator H10305.
The difference is in the lower outlet tube. They do not interchange with non-supercharged.
