Just put a new clutch on my 73, both pressure plate and friction disk, and a new pilot bushing, and just like the one I removed, it seems to drag after I have been driving and shifting some miles. Is this because the friction plate is made of a new non-asbestos material?

Do you mean it's not disengaging all the way?

Did you turn the flywheel? Install a new throw out bearing?

Of course.
I’m not going to assume you did, hence me asking. You may be surprised to learn that most don’t
A) turn the flywheel
B) install a new throw out bearing

When performing a clutch replacement. All too many are penny wise and pound foolish when it comes to auto repair.

I’m assuming you either have pulled it back apart or plan on doing so (correct me if I’m wrong). Please let us know what you find and determine the problem to be.

It is difficult to get into first gear without grinding, unless I first shift into 2nd then right away shift into first. Cold, it doesn't do that, it slips right in.

Does not want to easily go into first unless I first shift into 2nd, then immediately into first. The 2nd to the last clutch, which I assume had a friction plate that had asbestos in it, didn't do that, it shifted the same whether hot or cold, but the last one would act up hot, and this new one seems like its doing the same thing. That's why I was wondering it the new type material is to blame.

I've been just living with it, as I have the big heavy duty trans, we have moved and I can't find my transmission jack, and the trans is too heavy for my 70 year old azz to slide out by myself.

People actually try to re-use an old throwout bearing? Penny-wise and pound foolish for sure.

@JBswth so this is a granny 4spd (sm465), correct? If so, 1st gear is not synchronized like 2nd through 4th so by design it will not just fall in to gear.

This sounds like a pilot bushing or alignment issue to me.

I would ASSume that he means 1st road gear, rather than low gear.

I ASSumed first gear = #1 gear.
We are also assuming he has the old original granny low 4 speed.
This is why complete descriptions are important.
Nonetheless a couple things are true.
1. Has nothing to do with asbestos content of clutch lining.
2. IF it’s a non synchro 1st then the behavior sounds normal despite whatever past experience being compared to.
3. IF clutch engages and releases fine and otherwise works well it likely ain’t the new clutch. And possibly normal.
