Seems there are 3 or 4 different drag links. Was there a cutoff by year for a particular drag link? What is the difference in length? Have a 1920 frame for a speedster project. Thanks..

Mark,

Recommend you also look at Royce's posting at: http://www.mtfca.com/discus/messages/257047/300409.html some of the information is repeated but the photos and additional information make it very clear -- if you use all the parts from the same year (year range often times) and set it up stock you will not have problems. If you mix and match parts -- you need to be sure it will work correctly and not go over center etc.

Example of successfully mixing and matching parts -- see the posting at: http://www.mtfca.com/discus/messages/29/25924.html Look at John Sizemore's speedster -- the tie rod is in Front of the axle (don't hit a post...).

Not requested -- but you may find it helpful for your speedster project:

Also check out the technical information on the North West Vintage Speedster site at: http://www.nwvs.org/

Good luck with your build and be sure it is safe. It can be more exciting if it is not safe -- but the excitement is too often too costly.

Respectfully submitted,
