Very cool!! Keep us updated

Did some beginning mock up today but ran into a snag with parts I had accumulated. The tube axle I have has a 2" long kingpin boss, and the stock Anglia spindles I have are only spaced for a 1 3/4" kingpin boss. I'll check the axle's kingpin angle tomorrow but saw that some spindles are advertised as 7.5 degree kingpin inclination and others say 8 degrees. I've kind of settled on Strange spindles since I'll have to buy a pair if they will work with my axle. Are there actually axles made for both 7.5 and 8 degree kingpin boss inclination? Or, did some spindle manufacturers just round 7.5 degrees up to an even 8 degrees in their specs?
I also found a post doing some searching that stock Anglia spindles are made for 10 degrees of kingpin inclination, so even if they would fit the boss on the axle I have the camber would be off by 2 - 2.5 degrees. Could someone confirm? I doubt if anyone makes an axle any more that will work with stock Anglia spindles, do they?

Here is another option (see link) for using your existing tube axle with 2" long kingpin boss. These new "Stiletto Spindles" are for a 2" boss and cost less than the Strange. Plus watch out for the Strange spindles that are adjustable height, I think they are 3" length. You do not want the adjustable Strange spindles for your dragster front axle.

If you prefer to use your stock Anglia spindles, the Chassis Shop sells new Pro Werks axles that have 1.875 inch bosses. Refer to the advertisement with "SPE Axle" in the headings. And before you purchase, contact the Chassis Shop Company to verify your stock Anglia spindles with work with their new SPE axle. Here's the link:

These Pro Werk axles are all 8 degrees. I know you are wanting to build a 60s style dragster. The front tire cross-section for a 60s style dragster is different than a front tire for a modern dragster. Are you familiar with an Avon Speedmaster tire used prolifically on front engine dragsters in the 60s? Their contact patch (more rounded) is different than a modern dragster front tire which has a very flat contact patch with the road surface. Use a new front tire similar to an Avon Speedmaster cross-section and your question of 7.5 or 8 degrees inclination related to camber will not be a factor for your dragster build. Original 10 degree Anglia spindles, I'm not aware of but it's possible.
If it were my decision, I'd prefer using the stock Anglia spindles, they fit the 60s fed theme better.
THE FRENCHTOWN FLYER:
KINGPIN INCLINATION and CAMBER are two totally different things. It is possible to have a 10 degree kingpin inclination with zero camber. It is (theoretically) possible to have 10 degrees camber with zero kingpin inclination.
As denverflatheader alluded to the difference between 10* Anglia inclination and aftermarket inclination probably has more to do with tire size and wheel offset. Truth be told either set of spindles is likely to wotk just fine on a dragster. Good luck.

Thanks for the replies and information gentlemen!
I did some checking today and it seems the information I found that suggested that stock Anglia spindles have 10 degrees of built-in inclination in the relationship of the kingpin and the axle stub itself was just bad, incorrect information.
I first talked with someone at the Chassis Shop about the Stilleto spindles and he said that with shortage of workforce and materials he didn't know when they'd have spindles available. So-o-o...... I ordered a pair of Strange spindles which should install on my current axle with about 1.2 degrees of positive camber. That seems reasonable. Bad news is they probably won't be ready to ship until about the end of the year. No problem.....I have plenty other things to do to make progress! In the meantime I'll talk with a couple friends who have better tube bending and machining capabilities and equipment than I do to possibly build an axle to use my stock Anglia spindles. After all, I have several weeks before Strange is ready to ship. ;D And quoting you, denverflatheader, "If it were my decision, I'd prefer using the stock Anglia spindles, they fit the 60s fed theme better." I couldn't agree more!
Thanks again for the input and info. I sincerely appreciate it!
