Here's the Madiera Maroon...(I think)

Compliments of Kevin!

Humm..........Look at the difference in the Alternator Brackets between the Maroon car and Jody's Black 66 425 H.P. car........Are they both correct.....Early vs. Late etc.??????

The bracket was probably cut. GM didn't make one like that. The bracket in the 2nd pic is correct. My favorite GM mole can't find any documentation to support that short design. Cutting it like that weakens the support for the alternator. Things twist under load. That's why they changed it from the 1965 design. You don't want to have belts flying around at 7 grand! Since we're picking, the upper heater hose nipple on the intake isn't factory correct in the 1st pic. 2nd pic (Jody's) is factory correct. I guess Jody or previous owner added the engine chrome.

Ken, the bell housing should be #3872444. Fan looks good. I've seen 2 designs. That's one of them. Why so many digits in the part number of the crank pulley??

-----Im not sure if Im seeing things correctly, but it appears as though Jodys car has the bolt missing from that correct alternator bracket that would go thru to the intake. That would promote a bunch of twist as well!!!........Bill S

It's there, just barely peeking out from behind the upper radiator hose.

Mark,,, My eyes were telling me that the hole was unfilled and I guess I was somewhat right. The hole I was looking at was unfilled, just was looking at the wrong hole. Thanks for pointing me in the right direction......Bill S

kwhizz it looks like you know what you are doing here, just a heads up on the speedo cable. if you decide to go with the original type speedo cable that enters the trans on passenger side, don't forget to drill the 1" hole below the accel linkage. there is also a dimple on the passenger side of tunnel for the cable bracket to drill. also i found that i could not just change the tailshaft housing on mine because the speedo drive gear on the M-21 main shaft was not in the same place. not sure if that applies to all M-21 trans? dennis
