The 86-93 S10 4.3 TBI throttle cable should work... not sure about the bracket.

I ordered a regular anodized aluminium one for a carb that was red, and modified it for the stock cable. Dont get a lokar cable whatever you do, they friggen suck.

This is what I ordered:
Part #

29086 Vic Jr. w/ fuel rails
TC1000636 Lokar cable(cut to fit)
15152 Jegs throttle cable bracket
M592438 intake gaskets for Vic jr.
RGR501 fuel rail kit from Speed Inc.
9749 (2) 45* elbows
9849 Spectre carb hat

Take your Map sensor off you intake and the Victor Jr. will come with a bracket to mount the MAP sensor to the back bolt on top of the intake before you bolt on the throttle body and you just run a hose from the sensor to the intake...........

I need to get a pedal and Throttle cable for this super vic setup. I was planning on getting a Lokar pedal and their throttle cable. However, not sure if I will now. I spoke to them this morning and they did not have a brake for the cable mounting to the motor. Any ideas on a pedal and cable recommendation?

Im using a regular oem throttle cable and using a lokar cable end to adapt it to the 4150 throttle body. This was the cheapest option if you already have the correct gen gm cable.

Right now I do not have anything. I need a pedel, cable, and I think there is some bracket that I need that will bolt to the motor. Also my throttle arm on the 4150 is striking the underside of the air filter. I guess once I get it outfitted I can just cut the top of the arm on the 4150 to clear the air filter?

I am just trying to figure out how I need to set this up and the parts I need. This is my first setup. All help is appreciated.
