Backers of a new museum to celebrate motorsport hero Jim Clark have until 21 April to find around £250,000.
The new facility will cost £1.6 million to build, and £620,000 has already been pledged by Scottish Borders Council.
The Heritage Lottery Fund is also backing the project, and has agreed to provide £645,000.
However, for the project to be given the green light, the remaining money needs to have been pledged by 21 April.
The Jim Clark Trust has launched a Crowdfunding appeal to raise the money, and more than £58,000 has already been donated.
The project also has a selection of high profile backers, including John Cleland, Sir Jackie Stewart, Allan McNish, David Coulthard and Dario Franchitti.
Most recently, former FIA Ladies World Rally Champion Louise Aitken-Walker MBE pledged £250.
The new Jim Clark Museum would be a fitting tribute to remember a true sporting great.
The Jim Clark Trust has planning permission to build the museum in Duns, in the Scottish Borders.
