Many years ago I build this plane and used Carl Goldberg retratcts as shown on the plans, they worked well. You might find a set at swap meet.
He is looking for retracts for the Top Flite Bonanza. Bet you had a SIG Bonanza. No way in the world C/G retracts would work in this bird, if they were still available.
You can probably find some cheaper retracts, but it may not be worth the headache to retrofit, and they might not hold up.
