Since we're talking chassis I'll offer up for sale an IRS TR4A bare
frame that I have. Looks like I'm getting out of the TR4A business as
I've already sold the TR4A wreck I had and I'm in the process of
trading the Project (below) for an RV to use for pulling the Spit to
vintage races this year and MAYBE to Wisconsin in September.
Pics are available. The frame is solid (Jim Gray can testify) but I
haven't really checked it for any of the cracks being talked about so
I can't guarantee that it doesn't have any. Make me an offer.
