Hello

I am trying to upgrade my '69 Charger 8.25 with a limited slip w/ 3.55's. I purchased a limited slip carrier from e-Bay 27 spline casting # 18-05-039-0901.
I can hardly make out the last digit - "1". I read that if the last digit is a "3", it will not work in an 8.25 without a custom made 7mm spacer for the Ring gear, and custom made longer left hand thread bolts. I cannot find any info about a Sure Grip with the casting # above. Any thoughts? (Besides scraping my Small Block drive train) Although, if I had the $$ I would make my car an RT Clone. :D
