Mine is also a Lakewood scattershield that I bought used years ago. I came out of a Big Block Arrow . Fork is a typical big block short fork. The hole in the bellhousing is still 4.80" so I could bolt an A-833 back in here by changing the disc, throwout bearing, pilot bearing and driveshaft. The only modification to the bellhousing is to redrill it and weld nuts inside for the Tremec pattern. The ONLY work that I had to farm out on my swap was to get the Tremec bearing retainer turned down from 4.850 to 4.806" or so. EVERYTHING else in over-the-counter parts store stuff.
