Big chief
The spec you looking for is NHRA/SFI Spec 2.5C you can contact the SFI foundation @ :
SFI Foundation, Inc.
15708 Pomerado Road, Suite N208
Poway, CA 92064
USA
Phone 858-451-8868 Fax 858-451-9268
Email sfi@sfifoundation.com
They will sell you a copy of the spec for $35.
Mine is a S&W kit car that I purchased in 99 and it meets this spec.
Check the blue & silver tag on your chassis it should indicate this spec also.
Hope this helps!
