I am interested in some new Valve covers and a rear differential cover. Does anyone know where I can find some valve covers that would be chrome or aluminum with either "Chevrolet" or "350 Chevy" or something similar on them? I am also looking for a read diff cover, either aluminum or chrome. I've seen some black and aluminum striped ones that look nice, but have no clue where they came from. I've looked at LMC and JC Whitney, but they don't have much for my truck. Any other places to look at? I have a 98 body style K 1500 with the 5.7 350. Thanks!
