I hope this is in the right section, my current task is kinda odd but maybe not. I have looked through various threads and see a lot differing opinion on this problem so I am posting up to hopefully get some straight advice. The car is an '87 LX Interceptor that has been fitted with an Aussie block 351 punched to 408. The builder strapped a fully prepped C4 small bell with 157 tooth ring gear to it. Here's the part you knew was coming, they used a Ford Performance mini starter (50A) and it came in grinding the hell out of the starter drive. I have discovered that if I remove the lower bolt and shift the starter outward in it's plate mounting hole, I can then get the starter drive to engage and release from the ring gear in acceptable fashion. I had removed the solenoid to allow me to manually actuate the starter drive. My question is, does somebody make an offset bolt or bushing and bolt setup to make this correction. I saw mention of somebody using a smaller diameter bolt but he could not keep the starter from shifting around in it's mounting due to torque loading during starting. Thanks for the forum and the advice.
