I thought you might be interested in the test fit I did today on the big end bushing in Penelope. She's a genuine Lister 6-1 and I bought an Indian set of bushings from Troy. I plasti gauged it today, torqued to 68 ftlbs with no shims. The results were the same each of the 3 test fittings using green Hastings Plastigage, approx 0.0018 " . Since the min is 0.0015 and the max is 0.003 I guess they fit pretty well.
Just thought you might be interested.
