It's a tight fit and the tolerances on these cars are like +/- 1/4". On some cars there's no hammering and tweaking, on others there are. If I ran stock torsion bars with an automatic transmission on my car there would have been no dimpling or tweaking at at all with the Doug's. But I run 1.12" bars with a 4 speed and use a milodon road race pan, so, my options were limited to adding some small dimples for my torsion bars.
I'm using stock spool mounts with polyurethane replacement inserts. I have a V8 spool K frame. I haven't taken a survey or anything, but it seems to me that folks that run spool mount K's seem to have better luck with Doug's compared to TTI's. I'm sure there are exceptions, because with the factory tolerances these cars had there will always be exceptions.
I love the Doug's on my car, I wouldn't buy TTI's again. Just not very impressive for the price, the coating looked like cheap aluminum spray paint. You can get the Doug's from Autozone sometimes with a 20% online discount that they run.
Yeah, ok. And everytime you adjust the depth of the slot you're going to have to pull the engine and headers or drop the K frame while supporting the engine to either get in there with a MIG or a grinder (or both). And you won't get it right the first time, so, you're going to do that a couple of times. Yes, sure, I see your point there are ways to adjust the engine height with the spool mounts. But that's not anywhere near the same league of modification as adding a shim or two under the biscuit mounts. And on my car at least there's nothing that a 1/4" up or down would have solved anyway. But I have a few complicating factors with the size of the torsion bars I run, plus the 4 speed linkage, road race pan, different shape to the flaming river steering box, etc.
