Does anyone have the part number for the 5 bolts that mount the tranny onto the engine?? Also, I am looking for the long harmonic balancer bolt (LS7, I believe) number, too?? I tried using GM Parts look-up but had no luck.

For the transmission from the F-Body catalog:

98-02 LS1
M10 x 1.5 x 40
14050422
4 needed

Looks like it's no longer available but there's your size.

The LS7 damper bolt is available from ARP, 234-2504, M16 x 20 x 5.225 inches. $38.69 at Summit.

Thanks for the info.
I was hoping for the the GM number for the long balancer bolt. I heard they are fairly cheap and I just need it to get my LQ9 balancer started (on).

Thanks man. That is appreciated.
Your '71 Monte sounds bad a$$.
I had one about 20 years ago...a '72.

AWWW, this old thing?

Yep...that's it .
A great sleeper...especially for 600hp .
The engine compartment is huge, on those things. I've heard the car is on a Chevelle station wagon frame.
Mine was blue, also...quite a bit darker though.

Yhup, with electric fans, there's plenty of space to stand between the radiator and the engine.

The station wagon and 4 door chassis were 116 inches but extended behind the cowl.

The Monte Carlo & Grand Prix chassis was extended 4 inches in front of the cowl and another 4 inches in front of the A-arms. These were called "A-Special" frames.

The darker blue was Fathom Blue in '70 and Mulsanne Blue in '71. Mine in '71 was Ascot Blue.
