Ha, I’m guessing burnouts for distance and freeway cruising are not a problem for you! My subframe mockup trans behind the old 72 402 posted above is a T10 with the 6-ring input shaft and the super low 3.42 first gear. That’d make your old Maro roll out from a stop sign a little easier.
We’ve been collecting parts for years for this build and one of those old-school cool parts is a Mr. Gasket V-Gate shifter. I had a Hurst Ramrod inline shifter many, many years ago in a 67 Chevelle. Such a great car with a high winding 327, Offy crossram, Super T10, and a 12 bolt posi with 4.88’s. Just loved banging gears with that shifter so much that I needed another one. Truth be told it’s a big gawd awful thing that scares some folks, I dig it!
To run this shifter is a bit of a commitment, it can be a little tough (on your Nancy hand) pulling up on the lever for 1st & 2nd, it also takes a large hole in the floor and you can forget a factory console. No console means no console gauges (especially the fuel gauge), factory tach, etc. I’m ok running period correct style aftermarket gauges with the standard idiot light dash setup.
Talk about a commitment just had to take a grinder to my new M23 tail housing to make clearance for the reverse rod to function correctly. That gusset was not on the old Muncie housings and wouldn’t let it acuate reverse. Still need to figure a way to connect the reverse lever to a 67 Camaro backup light switch, but I’ve got some ideas.
