Thank you !!!
As far as the muffler goes, I'm trying to be as accurate as possible. These are the NHRA gasser rules from 1958.
1958 NHRA Rules for gassers:
3. Must have legal equipment required for operation on the street, including started & generator in good working order, & must be properly licensed for current year’s operation. Rear bumpers will be required in this division. Cars in this division must be started under own power. Fans & belts are optional. Radiator required.
4. Interiors may not be gutted. Must run full factory-type upholstery. Bucket seats (two) may replace front seats in coupes or two-door sedans, but be fully upholstered.
5. Must be equipped with mufflers suitable for street use. Headers with maximum of two head-pipes per car, will be permitted, but exhaust system shall be so constructed that mufflers remain on the car at all times. Header plugs or by-passes may be open during competition running.
