LHU Ecotec cradle mounts - obtaining / fabricating / welding (Page 2/2)

2 types of engine mounts for Fiero L4.
Liquid filled, Very real item, is/was for absorbing engine vibration. It works but often don't last long and liquid leaks out and rubber is dead.
Solid rubber. Looks about same but Much harder and won't go bad like the above.
See my Cave, Engine Mounts

If you have bad engine mount then very likely was liquid unit.

If Trans mount(s) are bad... is a different problem.
Most times have a bad Dog Bone or have a "new style" one. Ether will break trans mounts, exhaust, and intake parts.
See my Cave, Torque Strut

Can replace trans mounts w/ rubber and new one may or not have a torque limit feature in it.
If not or wants more control them short cable/chain across front mount to keep from torque tearing front mount.

My crappy health (heart) reared its ugly head again since posting the above.

In the meantime, I serendipitously came upon and bought an '84 Duke engine, transmission and exhaust mounted on a cradle from a Fiero restoration guy who had maintained it meticulously.

As my '84 SE has 33K miles and is in excellent original condition inside & out except for a busted connecting rod and the usual 1980s GM paint orange peel decay, I am going to install it in my '84, get it nicely painted and get 'historical' plates for it.

This way, I can have a decent Fiero to show and drive while I accumulate components to do the LHU conversion I planned, above. Along the way, I can accommodate my crappy health better, learn my way around Fiero engine handling and wiring and extend my investments in 'hot' Fiero components, so I can afford the fourteen GD medications I take every day, now.

It's still a fun journey, just a different path. I'll get there.

I wish you well Steve hopefully your medication helps you get better.

Good luck Steve, keep plugging away at it.
Hope your health improves.

Thanks for the kind words, folks.
I'll get where I want to with this. It'll just take longer, but I will.

This sounds like a great project. What transmission are you planning on using? I imagine your accelerator pedal will look similar to mine. It is from a 2013 impala, my donor car.
