Hey all, I'm putting the last bits and pieces on my 70 skylark custom big block conversion and I'm a little confused on what trans dipstick/filler to use. As far as I can tell there seems to be all different lengths for a GM TH400. Anyone know what length I need...is there a specific one for a BOP trans and where can I get one?? Also I'm looking to buy an inspection cover if anyone has an extra laying around. Thanks guys, Charlie
