When I do swap my 4 speed back into the car I was considering installing the later through bolt style of rear transmission mount in the car. I didn't know it if the later cross member is a bolt in or if I would just need to modify an early one to accept the later mount. The later capture mount just looks a lot more robust to me. So is this worth doing or should I just run what I got.

If you get a poly version of what you have it will be fine.

I have that mount in the Ruster with transbrake and I had it in the '69 Dart with slicks and 3400# car - Never gave me problems


If you want to swap to the spool mount, then I believe you will have to mate the spool to a new transmission member. I am not certain on this however.


Good Luck!

Every time I look at the single small bolt at the base of that mount I ask myself why. There is no reason it could not have had two bolts there or at least a larger single one.

Thanks Greg!

Greg's right. Assuming a good-quality part, even the rubber version of the stock pre-'73 vertical-shear trans mount is quite durable. They go for decades. Best spend effort-money-time elsewhere.

Possibly, But I won't be driving it like grandma's 100HP grocery getter either. Thanks for the opinions.

IIRC, the later spool mount crossmember will need some tweaks to make it work. Should be child's play for you.

There is a 2 bolt version of that block mount too.

I was wrong.

The spool mounts were made in the 4 hole trans member.
Not sure of the changeover year.
Bolts went from 1/2"ø to 3/8"ø.

Not sure if the holes align up or if futzing nerds to be done.
