EL CAMINO Cruise Control Servo Bracket/Assembly for a 350 SBC - pics included

[HK_Camino]

1986 el camino with a 350 sbc. I want to get the cruise control working again. I've seen pics of the servo assembly attached to the AC compressor via a bracket. Is anyone familiar enough to ID the pics below as being compatible with a 350 sbc?

The description is "84–87 Chevy GMC Pickup 84-91 Blazer Jimmy Cruise Servo GM25031447 W/Brackets SBC"... seems appropriate

Also! I am installing a sniper EFI system. My research says the factory Cruise Control still works with the EFI system, but if anyone has experience otherwise please let me know before I dive into this project lol.

The assembly that is shown in your pictures would have been mounted to the back of the driver's side cylinder head. How so? Well, if you pick it up, you have the main bracket that mounts and supports the "motor" and to that bracket is screwed a second bracket that, you will note, has the square shaped holes that are the anchoring points for the throttle and TVS cable punched into it. Attaching it to the motor would be by that "Ell shaped tab that is pointing up in the picture; it would likely pick up one or the other of the two rear bolts for the intake manifold same as the one that might be there now, and on the main bracket, hidden by how the unit is sitting, down at the bottom, there would be a stepped flange with a forked or fingered end on it. That would slip under a short 3/8ths bolt screwed into the upper hole? in the back of the head. Muy mas fun to get at with the motor still in the car as it all butts right up tight to the firewall.

On the head of the controller, you can see the vacuum ports and on the bottom is the plug for the wiring harness, If you don't already have that circuit resident in your engine harnesses, save the plug because you should be able to open it and replace the cut off stumps with clean fresh leads bearing the correct terminal ends.

Thanks, great information. sounds like it could work, but will be a hassle with the engine in the car. I'll have to take a look later and see what bolt holes are available for the bracket and how much clearance I have.

If you can reach in behind the head and identify the right hole for the back mounting bolt, then you ought to be able to finger start that bolt a thread or two. 3/8ths x 1/2" NC or maybe 3/8ths x 3/4 NC should be short enough to sleeze into position. After that, because that leg of the mounting bracket is forked, you can just slide the mounting ear over the bolt.

As for getting it tight, my suggestion would be the use of a "GearWrench" style ratcheting combination wrench in 9/16ths. They have a fairly thin/slim profile which makes getting into tight places a little easier and being able to ratchet lets you put turns on the bolt head without having to reset the wrench. If you can get the wrench end on the bolt while it is still loose, you should definitely be able to retrieve the wrench once the bolt is nailed down. This model of wrench can be had as a single item or as part of a range in a kit.

Just a thought.
