For non-kdss which seems like it should be the same the stock pan is held on with 4 8x20mm with attached washers. - looks like the parts listed above for 9008011373 - 1.29$ US
Front plastic has 2 6mm bolts + push pin
4 10x25mm bolts are the ones the TRD plate replaces - might not need those if they stayed in.
8 and 10mm look to be 1.25mm pitch
