Need to purchase a new flywheel, and various back of engine and transmission related parts. Which is better to deal with? Brewer or Passon Performance?

And if I have a B body with a hemi 4-speed, it should be an 11", 143 tooth flywheel, right?

What year and engine B body? 66-69 Hemi equipped 4 speed cars used a 172 tooth flywheel.

1969 Plymouth GTX w/440. New engine will have a 8 bolt crank flange, 4.25" stroker. I remember years ago trying a factory aluminum bell housing. But flywheel would fit, so figured it'd be an 11". 143 flywheels mention. "neutral balance crank". 172 tooth gear mentions "hemi motors using original direct drive starter". I have and will use a mini starter for header clearance. Please advise.

Look at the casting number on the lower right hand side of the back face of the bell housing facing the trans. and post it on here if you can't find that casting number application.
I'm assuming it is a cast iron bellhousing and not an aluminum one, correct?
The casting number will tell you the year and clutch and flywheel size that fit into it stock: scope:

Brewer's IMO I have dealt with both!

69 440 B body would use the 143 tooth flywheel. Not normally a hemi flywheel, but I do think the aftermarket supports one with 8 bolts.
In 1970 mopar went to the 513 Alu Bell house for the 130 tooth flywheel for all BB motors including hemi.
But as stated, the actual Bell housing determines the flywheel size so that the starter engages.

I have spoke with both and used brewers when I did my 4 speed, my good friend also used brewers on his hemi box. Great parts, great people, and they are kind enough to help you through any issues you may have. They are my choice Hands down

I've bought several items from Brewer's and have been happy with them every time.
Knowledgeable, reasonable, correct and quick works for me !

I’ve dealt with both. Brewer’s is my choice, bought a complete 727 to A-833 swap from them

Both Brewers and Passon are experts for the Chrysler 4-speed hardware.
But U need to check closely product availability, in today's market things can change very quickly.
We have bought from both vendors, as they valuable supporters for our select Mopar cars.

Just my $0.02...
