Charlie,
MrmodelT (Clayton) and I have built our two cars on a very limited budget with leftover parts. Clayton's roadster started out as a parts car we had inthe back corner of our shop my car "the Becker Special" started as a spare frame and firewal and we built a plywood body and fiber glass fenders for it .
Here is links to our build threads on the HAMB forum:
Clayton's build of Joesephine his 1926 T roadster check out the later postsas we comletly rebuilt the car to correct suspension and drivetrain problems that plagued his car on the intial build ( by the way drove his roadster from Portland Oregon to Wendover Utah for Bonneville Speed Week round trip 1732 miles under it own power)....

Here is the link to our car The Becker Special. Read the background story for the special, shewas intended to be my dads car but he never saw it done... We built her a real tight budget with spare parts and lots of ingenuity. Tried drive it with Clayton to Speed Week but broke crankshaft. Now we just finished a year long rebuild of her and had the first drive in it this last weekend.....

Get Murray Fahnstock's book Model T's in Speed and Sport that will get you started and check out some of the other Gow Jobs build threads on the HAMB as there is quite bit old tech stuff being unearthed by the traditional hot rod movement. Also check out the Northwest Vintage Speedster boys as they are keeping speedsters in the limelight....
