Welcome to the world of building Tee Buckets.
Theres nearly as many ways to go about it, as there are buckets out there, but from my mistakes I can recommend the following (I have started 8 buckets over 30 odd years & most were failures):
- Begin with the end in mind.
- Plan to do everything only once
- Figure your theme and stick to it
If you get any of those three wrong, then you either end up with something you arent happy with, or you eventually end up with something you are happy with but it will be 200% over budget.
And so back to your plans.
You have a stance/rake in mind. So lay out the frame in your garage using axle stands and blocks of wood. You need to know the rim & tyre sizes you are planning to use. If you dont have the wheels yet, then either borrow some, or make some the size you want from ply. Its only to mock up so dont worry about the ply. Try going to
www.whitewallcandystore.com as they have lots of details on tyre heights that will help you.
hopefully you also have your Tee body at your place. You need to sit it up on the frame and then stare at it for ages and adjust the exle stands till you get the rake where you want it to be.
Then assuming you have an engine, you need to figure how high it needs to sit in your frame. Oil pan bashing isnt a cool thing to do. So set your engine up in the frame using an engine crane and check for clearance underneath.
If the chassis is super low, then the engine will probably need to sit high to avoid pan bashing. With a high engine in a low chassis you will have less footroom, because the trans will sit higher relative to the floor.
Then stop for a beverage of your choice and stare at your creation for at least 30 minutes. And decide if thats what you really want.
Once you have that pretty much sorted, you can look at the front end and decide what level of drop you need in your axle. It may be that a lesser drop will work if the spring perch is mounted higher on the chassis, or iy you mount the spring atop of the perch.
Anyway thats just for starters. good luck with your project
