Mid-Atlantic Customs in Maryland has done 2 E body convertibles for me. They are excellent. Both took around 6 months to get through the shop. They can be found on facebook. Excellent body and paint work and mostly MOpars.

Have you ever operated a manual top? The manual top pistons have springs in them. So one person can easily put the top up and down. I have both manual and a hydraulic top E-body convertibles. To me they are both easy to put up and down.

I have an original 1970 Dana 60 for an E-body. If interested, I can message you a link to pictures which show the numbers and dates. It has 4:10 gears that are date appropriate but the numbers say it should be a 3:54 gear set.
