I have been using the Delco professional top post model 36H6YR.....fits like an R59 and the topper goes on well. Also took a "real" sidepost from the day and "gutted" it. Planning on using a small hi-po style battery inside and connecting the terminals and then fabricate a bottom. As for the repro sealed or acid style...you can keep them! Only thing I would ever use is an acid style without the acid..just for looks. Those things are just time bombs waiting to go off!
