Cobey.....you don't need no stinkin' soft top
.....just a wind tunnel anyway (tonneau is nice)....just get a nice Thinsulate head warmer.
With a BB, you don't need no stinkin' 5th gear either, depending on the rear-end, unless you're planning on cruising routinely above 100...hope not! Mine's a 3:31 Jag, and a good balance with all that torque. Toploader's rock coupled to BBs!
Also, why don't you ask Cherner to put that car on a lift, and get you the date of manufacture numbers from that SO block, just above the
oil pan near the
oil intake near the front driver's side of the block. Also, ask them to look for numbers below the heads on the pass. side of the block, which may or not be present. Will at Cherner know's where I live, and they can put it on the lift in my garage if they want with you present.
I can help you identify the heritage of that motor, and if it's a service or replacement block, they may be willing to sharpen their pencils a lot more. No matter what, if it's a real SO, then it's a desirable motor, but it's hard to tell without getting underneath it.
