Mine are all sagged out and I need to stiffen up the rear, anyone have a line on drop in replacements? Not looking to lower the car at all.

I have a set of rear springs for 71 142 that I took off in 1977. They are in storage, how soon do you need them if interested.

Are those going to be stiff enough for a wagon? They the early style still?

Not in a rush.

"Are those going to be stiff enough for a wagon?"

I'm gonna jump in here and give you an opinion, based on what I see in the factory service manuals. The 142/144 rear springs are softer than 145 rear springs... about 25% softer to be exact. I don't think I would do this.

And while we're at it, with respect to using 245 rear springs in a 145, the service manuals show an even larger rate difference between those two (about 30% higher in the 245). In this case, I'm looking at what is shown in the factory manuals for a '71 145 vs the '75 245. This is a bit curious IMO, since I don't think there would be a significant difference in the unloaded (curb) weight on the rear wheels of those 2 vehicles. And this difference does not show up when you look at '71 sedan vs '75 sedan... only a 3% bump-up. Maybe the advertised carrying capacity of the wagon was increased significantly at some point after '71?

Anyhoo, Scandcar.com (and probably others) shows a catalog listing for 145 rear springs.

Thanks Gary, I was going to compare the spring rates, you saved me a lot of fruitless googling :) Yeah, stock or better for the wagon is what I need, I plan on hauling stuff with it.

I found my IPD catalog, and it'd be 160 for the springs+brackets+rubber mounts before shipping. Would like to keep it lower than that.

I see on scandcar they are 38 euros each for the springs..IPD isn't that bad then in comparison. ($100 a pair)

I'll jump in here too--as I've had a lot of experience swapping out springs (sometimes for carrying capacity, sometimes for performance)in 140's. The 140 wagon's springs are stiffer than the sedan by a substantial margin--the 240's a little stiffer still (they are heavier), but not so stiff as to adversly effect ride when put into a 140. Years ago I worked for a used car dealer as a mechanic/sales guy and didn't care to leave my tools at the work location -- carried them around in the trunk of a '68 144. Here's how I handled the load -- went to Home Depot (or equivalent) and bought a stack of large industrial washers and a stack of smaller ones to fit inside the larger ones and a couple of 3/8" diameter graded bolts and nuts. I smacked the welded stud out of the lower spring retainers and replaced them with the bolts. Stack the washers to whatever height you need to level things out--in my case that was about 2 inches. Never a problem in over two years of commuting 60 miles a day. As a final note I'd like to thank Joel (Antique S-S)--Months ago I swapped my GT dash panel for his old lowering springs, for my '69 Time Trial car -- worked out great and now that my son has finally seen fit to send me the digital pics he took at Summit Point Raceway I'll send Joel a nice cornering shot to show how well they worked with my own sway bar setup.

I'll have to take a look at it. My old 68 Jeep truck uses post mount (leaf) springs and we have the same issues with those..(bit scarier in a 5000lb truck)

240 is the later model sedan, right? That would work with the cups swapped, I guess I put up a wanted and see if anyone's sitting on a parts car, not many around here.

Springs from a 200 series will work as long as you use the upper 200 series mount - which is a bolt in.

I have IPD overload coils on my 145 and 745. In my opinion, they give a slightly stiffer ride when the car is empty. Overall, I've been happy with their performance.
