I contacted ARP and told them what the FoMoCo bolts sizes were originally, and they emailed me these part numbers for their replacements.
HAP4.300-5 7/16 -14 x 4.300"
HAP4.060-5 7/16 -14 x 4.060"
HAP2.180-5 7/16 -14 x 2.180"
Washers APW1316
I contacted them today and will get them Thursday, which is great.
Just before I called them. I called Mummert for the 3rd time. I called him on the 1st (said he had bolts in stock but no washers and would call ARP), called the 14th (said he still had no washers yet so I gave him my CC# and he said he would ship out just the bolts). Again, after no CC charges for a week I called him again today and said he wrote all my info down but he said "I did not send them yet but I got some stuff from ARP Thursday so I can send them!!!". Well lying and blowing me off for weeks was no bueno. I asked him after calling and being told he would send them, What's the disconnect? He just said "It is what it is, you want them?" I wish I could have reached through the phone.
I will probably grind off his name from the intake and the valley pan cover while I got them off so I do not advertise him at car shows. EABODs
