3k & 4k lifters are the wrong size, what you what is the 5k or 3f landcruiser lifters (same part no,s) also holden red (202 etc) or small block chev will fit, ok if your not running high lift cams. with soild lifters you can use the 4k push rods if you have the 5k flat top piston head, with the dished piston head toyota do make a push rod (4k) but you have to buy them new.
also my epc covers supercedes, its probaly a part number they pulled out of microcat - australia only listing
