Here is the updated list by NHRA in Jan. 08 of the accepted suppliers and also the classes that require the diaper. The only problem i see is that i believe next yr. the rule will change and some of the faster classes will require a SFI certified.
The other problem is, if you are running a regional or national event and have an oildown, no matter if you are required to have a diaper or not, you will be fined and that fine is $150.00 the first time even in the sportman classes such as S/ST--Stock, etc.
