For our Dodge NASCAR R5P7 engine, there is NO available scattershield..... NASCAR does NOT require the use of a scattershield if using a small diameter Tilton or the like, clutch - they use a magnesium bellhousing - and NOTHING ELSE... we rolled up a piece of 3/8" X 6" wide flat bar into a full circle, welded it to several mounting lugs outside of the stock bellhousing and it meets the letter of the SCTA rule....
a little side issue on this point is fuel lines and oil lines in the proximity of the flywheel plane.... and the rule covering this topic specifically states these two choices - run the lines outside of the frame rail(s) or through pieces of pipe.... some inspectors look at this as being the ONLY acceptable methods..... the rules called for a 1/4" thick scattershield - we went to 3/8" thick..... 50% THICKER..... but NO, NO, NO!!!!! .... we HAD TO INSTALL YET more FUEL AND OIL LINE SHIELDING!!!!!! the thickness of the frame, then?..... I bolted another pirce of 1/8" thick steel into the inside of the 3/8" thick rolled shield..... ALL FOR THE PUTPOSE OF CONTAINING AN EXPLOSION OF A CLUTCH THAT NASCAR SAYS DOES NOT BLOW UP!.....Seniot tech people, later on, told me that it was NOT necessary due to NASCAR's exerience with the clutches NOT blowing up and the fact that a 3/8" thick shield fit the intent of the additional shielding in the flywheel plane area....
just so you know.....
