Front Springs - Monza

Looking for a different coil spring for the front of a '75 Monza. Stock replacement stuff is not going to get it. I need to remeasure but I think the stock spring pocket is 3.5 inches and I am looking for something that is maybe in the range of 275-300 pounds?

I think they used to use rear springs from a Corvair back in the days before the V-8 Monza. I have a copy of a booklet "How to build a V-8 Vega" at home somewhere. What are you shoe-horning into your Monza?

2x3 chassis drag car with original a-arm components utilized. Small block, iron/aluminum. The current coils are cut stockers and I need more energy. Like to put Moroso tricks in it but they will not provide dimension information. Wouldn't mind going with coilovers but don't have the extra coin right now.

Oh... something else you might look into is a set of early Vega (71-74) lower control arms. The spring pocket is shallower than what you have. I found out the hard way when I crammed a set of V-8 Monza springs in my '74 Vega. That might get you where you want to be without changing springs. I can do a little digging in my stash to see if I have any early arms if you want.

Might be off the path here a little, but there's a post I answered a week or so ago. There is a company than custom makes springs, might be a source for you.

Also in '86 I was part of a quality group looking at the change in quality of auto manufacture. This was the beginning days of JIT (just in time) processing, QS/ISO 9000, Ford's "Quality is Job 1" program, robotics, outsourcing and etc...

One of the issues is what was termed "Chevette and Cadillac Quality" one of the issues we specifically talked about was inherent quality standards and machining tolerances of front end parts.

One the team members was the purchasing agent that specialized in overseas procurement. A major topic in line with this was poor quality Japanese steel that was coming in at the time. Yours is a '75 which at that time, I believe was still USA sourced steel, but you might want to look at potential (future tense) going tube steel control arms. The Japaneses steel was failure prone under high stress events, which would be in the realm of launch and landings from any wheel stands or other high energy dynamic events.
