Question starter

[series700]

Hello dear B58 friends.

Sorry, I haven't been here for a very long time.
I've had my 1958 Buick Limited 4-Door door hardtop since 2015 and I'm finally done with the restoration.
The starter and batteries are of course also new, but the starter is very weak and makes it difficult to turn the engine.
Now my thought was to buy a gearbox starter with more power. There are offers from IMI Torque or Powermaster.
My question about this...
What kind of experiences have you had with it and can you recommend a certain model to me?

I would be very grateful for your help.
Sorry, the text is from the translator;-)
I still hope that everything is understandable.

With best regards from germany

Michael
